Square footage is the length of your room times the width. For a circular room, measure the diameter (length across the circle), divide by 2 to get the radius (length across half the circle), multiply by pi and square it. The formula for the area of a circle is πr^2, and Pi (π)= 3.1416

you use the formula: Pi x radius (half the diameter) squared.

You take half the area of a circle in square feet. The formula is: 1/2 * pi * (radius)2

Treat it as a square and half the result.

The radius of a circle is half of its diameter.

The same as half the side of the square, as the radius of the circle is half its diameter, and the diameter of the circle is equal to the side of the square.

the area of a circle is pi times the radius squared, the radius being half the diameter. Pi is approximately 3.14

The answer depends on what characteristic of a half circle you want to calculate: its area or perimeter or something else.

1/2 acre is 21,780 square feet.

70 square foot.

Assuming your aim is the largest semicircle within the rectangular area, it would be a half circle of radius 5.5 ft. A circle's area is Pi times the radius squared, so the half circle would be 1/2 * 3.14 * 5.5 * 5.5 , which equal 47.5 square feet.

1. Multiply pi (3.14) by the radius of the circle (half of the diameter which is the length of the circle on the widest part).2. Square your result.This uses the formula:Area=πr2where π=3.14

You calculate the circumference of an entire circle, then divide by 2.

Half the square root of the square radius equals the circle radius.

Half the length of a side of the square.

Yes, .5 of an acre is half an acre or 50%. The actual square footage would be 21,780.

Area of half a circle in square m = pi*radius2 divided by 2

It is not. If you draw yourself a square then inscribe a circle with a radius of half the length of a side of the square, the circle will fit inside the square but the corners of the square will be outside the circle. Thus by inspection the area of the square is larger than the area of the circle.

It depends on the diameter of the circle and the width of the square, if they are the same then the answer is no. If you draw yourself a square then inscribe a circle with a radius of half the length of a side of the square, the circle will fit inside the square but the corners of the square will be outside the circle. Thus by inspection the area of the square is larger than the area of the circle.

Well, since the circle is inside the square, the edges of the square define the limits of the circle. Since we have a square, the length of each side is the square root of 800ft. The radius of the circle is half the length of the sides. Therefore, the answer is half of (the square root of 800), which makes for an ugly radius value of "14.142135623730950488016887242097" ft

Convert the inches to feet (dividing by 12), then multiply. The result is then in square feet.
