804.25 square cm
The radius of a circle is half the length of the diameter, so if the diameter is 32 centimeters the radius is 16 centimeters.
A 32-inch circle has an area of 804 square inches.
The area of a circle can be calculated using the formula A = πr^2, where A is the area and r is the radius. Given a radius of 32 cm, we can plug this value into the formula to find the area. A = π(32 cm)^2 = π(1024 cm^2) ≈ 3216.99 cm^2. Therefore, the area of a circle with a radius of 32 cm is approximately 3216.99 square centimeters.
A circle with a radius of 32 inches has an area of 3,216.99 square inches.
We have to guess at what the question means where it says a "32 foot circle".-- Is the circle 32 feet in diameter . . . across the widest part ?-- Is it 32 feet in radius . . . from the center to the curve ??-- Is it 32 feet in circumference . . . around the curve ???We'll assume it's 32 feet in "diameter" ... across the 'widest' part.The area of a circle is [ pi R2 ] where 'R' = the radius = 1/2 of the diameter.pi R2 = pi (32/2)2 = pi (16)2 = 256 pi = 804.25 square feet (rounded)
384 cubic centimeters.
The surface area is 3217cm2
Area = 804.25 inches2
Area in square inches = pi*radius2
The area of a circle is pi * r2. The area is 32, so 32 = pi * r2 32/pi = r2 r = sqrt(32/pi) d = 2 * sqrt(32/pi) d = 6.38307649 inches
32 x 32 x 3.14 = 3215.36 sqyds
3215.36 square inchesArea of circle = π r2= 3.14 (32 inches)2= 3.14 (32 inches) (32 inches)= 3215.36 square inches
