You use the formula for the area of any circle:
Area = (pi) x (radius)2
and to find the radius to use in this formula, you remember that
Radius = 1/2 of the diameter.
A couple of additional helpful facts:
-- A convenient and quite accurate number to use for (pi) is 22/7 .
-- The correct spelling of "circle" is "c i r c l e".
To find the diameter of a circle given the area. The area of a circle = pi x the radius squared. To find the radius, then the diameter transpose the area formula, so A = Π * r^2 A/ Π = r^2 √A/ Π= r 2 x √A/ Π = d A = area Π = pi = 3.142 r = radius d = diameter
Area in square feet = pi*62
First find out the radius (it is simply half the diameter). Then use the formula area = pi x radius2.
9pi (about 28 and one quarter) square feet.
To find the area of a circle, you can use the formula A = πr^2, where A is the area and r is the radius. Since the diameter is 32 feet, the radius would be half of that, which is 16 feet. Plugging this into the formula, the area of the circle would be A = π(16)^2 = 256π square feet.

Well, darling, to find the area of a circle, you use the formula A = πr^2. Since the diameter is 26 feet, the radius is half of that, which is 13 feet. Plug that into the formula, and you get an area of approximately 530.66 square feet. Voila!
To find circumference you must multiply twice the radius by π, or using the diameter, if it gives it to you, multiply that by π.
First find out the radius (it is simply half the diameter). Then use the formula area = pi x radius2.
9pi (about 28 and one quarter) square feet.
To find the number of acres in a 2114 feet circumference, you need to first convert the circumference to a diameter. You can divide the circumference by Pi (3.14159) to get the diameter. Once you have the diameter, you can use the formula for the area of a circle (A = πr^2) to find the area in square feet. Finally, convert the square feet to acres by dividing by 43,560 (since 1 acre is equal to 43,560 square feet).
To find the area of a circle, you can use the formula A = πr^2, where A is the area and r is the radius. Since the diameter is 32 feet, the radius would be half of that, which is 16 feet. Plugging this into the formula, the area of the circle would be A = π(16)^2 = 256π square feet.
when trying to find squ. feet you have to find the area. the area of a circle is half of the diameter squared times pi half of the diamter is the radius therefore the area in squ. ft would be.. A = pi x r2
To find the diameter of a circle with an area of 1500 square feet, you can use the formula for the area of a circle, ( A = \pi r^2 ). Rearranging this to solve for the radius gives ( r = \sqrt{\frac{A}{\pi}} ). For 1500 sq ft, the radius is approximately 21.9 feet, so the diameter would be about 43.8 feet.
