What is the square footage of a 30 foot circle?

In terms of pi the answer would be 225pi ft^2.but if you want the rounded decimal answer it is about 706.86ft^2.

.

Also know, how many square feet is a 30 diameter circle?

Multiply the radius by itself to square thenumber (6 x 6 = 36). Multiply the result by pi (use the button onthe calculator) or 3.14159 (36 x 3.14159 = 113.1). The result isthe area of the circle in square feet--113.1square feet.

Also, how do you find the square footage of a round pool? Multiply the length by the width of the pool tofind the square footage. For instance, 15 feet(length) times 12 feet (width) equals 180 squarefeet.

Also, what is the square footage of a circle?

To determine the square footage of the area of acircle, multiply 3.1416 times the radius (in feet)squared. To determine the circumference of a circle,multiply 3.1416 times the diameter (twice the radius).

How do you calculate area of a circle?

The area of a circle can be found bymultiplying pi ( π = 3.14) by the square of the radius. If acircle has a radius of 4, its area is 3.14*4*4=50.24.If you know the diameter, the radius is 1/2 as large.

How do you calculate volume of a pipe?

The formula for the volume of cylinder is:cylinder volume = π * radius² * height . For apipe use its length instead of height: pipe volume =π * radius² * length , where radius = inner diameter/2 .The volume of a pipe is equal to the volume ofa liquid inside (if a pipe is fully filled withit).

How do we calculate area?

To find the area of a rectangle multiplyits height by its width. For a square you only need to findthe length of one of the sides (as each side is the same length)and then multiply this by itself to find thearea.

How do you measure the square footage of a house?

Just break out your measuring tape—or alaser measure—to get its length and width. Multiplythe width by the length and voila! You have the squarefootage. Say a room is 20 feet wide by 13 feetlong, then 20 x 13 = 260 square feet.

How do you find the square footage of an irregular shape?

How to Calculate the Square Feet of Odd Shapes

1. Measure all the dimensions or sides of the area.
2. Draw the area on graph paper using the measurements youobtained. Make sure your drawing is to scale.
3. Divide the drawing into shapes.
4. Figure the area of each shape.
5. Add the areas of all the individual shapes to find the totalsquare footage.

Is it possible to square a circle?

Squaring the circle is a problem proposed byancient geometers. It is the challenge of constructing asquare with the same area as a given circle by usingonly a finite number of steps with compass and straightedge. Theexpression "squaring the circle" is sometimes used as ametaphor for trying to do the impossible.

What is the area of a 12 inch circle?

So if the radius of the circle is 12",then the area "A" is (approximately) 3.14 * 12^2 orabout 3.14 * 144 = 452.16 square inches. If the diameter ofthe circle is 12", then the radius is 6" (half thediameter), and the area "A" is (approximately) 3.14 * 6^2 orabout 113.04 sq. in.

How many acres are in a circle?

The formula for the area of a circle is: Area =π * radius². If the radius is given in feet, the area is insquare feet. To convert from square feet to acres, divide by43560. So the acreage of a circular area is: Acres =π * radius_in_feet² / 43560.

How do you find the perimeter of a pool?

A round swimming pool can also be measured bylaying a tape measure around the outside edge of the pool.However, if you already know the diameter of the pool— which is the way many above-ground swimming poolsare sold — you can determine the circumference withthe formula: "Circumference = pi x diameter."
