4 to the second power is 16
and pie is always 3.14 so pie times
radius so multiply 3.14 and 16 and that is
your answer
50.24 answer
The area is 1,020 square inches.
Using 3.14 as Pi the area of circle is: 200.96
pi*10*10 square inches
Area of a circle is calculated by taking the radius squared times pi (3.14 approx.). 108 x 108 = 11,664 11,664 x 3.14 = 36,624.96 The area of a circle with a radius of 108 inches would be 36,624.96 square inches.
A circle with a radius of 18 inches has an area of 1,017.88 square inches.
A circle with a radius of 6.6 inches has an area of 136.85 square inches.
Area = Pi(r)2 - A circle with a radius of 25 inches has an area of 1,963.5 square inches.
The area is 1,020 square inches.
Area = Pi(r)2 - A circle with a radius of 12 inches has an area of 452.39 square inches.
Using 3.14 as Pi the area of circle is: 1808.6399999999999
Using 3.14 as Pi the area of circle is: 200.96
pi*10*10 square inches
Area of a circle is calculated by taking the radius squared times pi (3.14 approx.). 108 x 108 = 11,664 11,664 x 3.14 = 36,624.96 The area of a circle with a radius of 108 inches would be 36,624.96 square inches.
pi*25 = 78.5.
Area = pi*r2 Area = pi(12 inches)2 = 452 inches squared ================
A circle with a radius of 32 inches has an area of 3,216.99 square inches.
The area of a circle if the radius is 2.5 inches is: 19.63 square inches.
