This free area calculator determines the area of a number of common shapes using both metric units and US customary units of length, including rectangle, triangle, trapezoid, circle, sector, ellipse, and parallelogram. Also, explore the surface area or volume calculators, as well as hundreds of other math, finance, fitness, and health calculators.Therefore the shaded area would have a smaller area than with the hexagon. What is the area of a sector with measure of arc equal to 90° and radius equal to 1 foot? 0.5(PI) sq. ft.To calculate the area of a sector, start by finding the central angle of the sector and dividing it by 360. Next, take the radius, or length of one of the lines, square it, and multiply it by 3.14. Then, multiply the two numbers to get the area of the sector. For example, if the central angle is 100 degrees and the radius is 5, you would divideArea of sector. In a circle with radius r and center at O, let ∠POQ = θ (in degrees) be the angle of the sector. Then, the area of a sector of circle formula is calculated using the unitary method. When angle of the sector is 360°, area of the sector i.e. the whole circle = \(πr^2\) When the angle is 1°, area of sector = \(\frac{πr^2

To calculate the sector area, first find what fraction of the whole circle we have. Calculate theWith this sector area calculator, you'll quickly find any circle sector area, e.g., the area of semicircle or quadrant. In this short article we'll: provide a sector definition and explain what a sector of a circle is. show the sector area formula and explain how to derive the equation yourself without much effort.

With this sector area calculator, you'll briefly in finding any circle sector area, e.g., the area of semicircle or quadrant. In this brief article we'll:

supply a sector definition and provide an explanation for what a sector of a circle is. display the sector area components and give an explanation for how you can derive the equation your self with out a lot effort. expose some real-life examples the place the sector area calculator would possibly come in handy.

What is a sector of a circle? Sector definition

So let's get started with the sector definition - what is a sector in geometry?

A sector is a geometric determine bounded by means of two radii and the included arc of a circle

The footage under show a couple of examples of circle sectors - it doesn't essentially imply that they're going to look like a pie slice, occasionally it seems like the rest of the pie after you've taken a slice:

You would possibly, very infrequently, pay attention about the sector of an ellipse, however the formulas are approach, way more tricky to make use of than the circle sector area equations.

Sector area formula

The formulation for sector area is simple - multiply the central attitude by way of the radius squared, and divide via 2:

Sector Area = r² * α / 2

But where does it come from? You can in finding it by way of the usage of proportions, all you need to remember is circle area system (and we guess you do!):

The area of a circle is calculated as A = πr². This is a super starting point. The complete attitude is 2π in radians, or 360° in levels, the latter of which is the more not unusual perspective unit. Then, we need to calculate the area of a part of a circle, expressed via the central perspective. For angles of 2π (complete circle), the area is equivalent to πr²: 2π → πr² So, what's the area for the sector of a circle: α → Sector Area From the proportion we will easily find the final sector area formulation:

Sector Area = α * πr² / 2π = α * r² / 2

The similar approach is also used to search out arc length - all you want to remember is the formulation for a circle's circumference.

Special circumstances: area of semicircle, area of quadrant

Finding the area of a semicircle or quadrant should be a work of cake now, just take into consideration what phase of a circle they are!

Semicircle area: πr² / 2

Knowing that it is half of the circle, divide the area through 2:

Semicircle area = Circle area / 2 = πr² / 2

Of path, you can get the same result when the use of sector area system. Just keep in mind that directly attitude is π (180°):

Semicircle area = α * r² / 2 = πr² / 2

Quadrant area: πr² / 4

As quadrant is 1 / 4 of a circle, we will be able to write the formula as:

Quadrant area = Circle area / 4 = πr² / 4

Quadrant's central angle is a right angle (π/2 or 90°), so you can briefly come to the similar equation:

Quadrant area = α * r² / 2 = πr² / 4

Sector area calculator - when it can be useful?

We know, we all know: "why do we need to learn that, we're never ever gonna use it". Well, we'd like to turn you that geometry is throughout us:

If you are wondering how big cake you will have to order to your superior party - bingo, that's it! Use sector area system to estimate the dimension of a slice 🍰 to your visitors so that no person will starve to dying. Check out how we now have implemented it in our cake serving calculator. It's a similar tale with pizza - have you ever spotted that every slice is a sector of a circle 🍕? For example, if you're not a large fan of the crust, you can calculate which pizza dimension gives you the highest deal (don't fail to remember about the tip afterwards). Any stitching fans right here?👗 Sector area calculations could also be helpful in making ready a circle skirt (as it is not at all times a full circle but, you realize, a sector of a circle as a substitute).

Apart the ones simple, real-life examples, the sector area formula could also be handy in geometry, e.g. for locating floor area of a cone.
