pi x r x r = 82
r x r = 82/3.1415 = 26.10
r = square root of 26.10 = 5.109
Hence diameter = 2 x 5.109 = 10.218 inches
The diameter of the circle will be: 26.1 inches.
Area of the circle = pi*82 = 201.062 square inches rounded to 3 dp
Formula for finding the area of a circle: Area = pi * r2 a = 3.14 * 82 a = 3.14 * 64 a = 201.06
Diameter = 16 inches so radius = 16/2 = 8 inches. Then area = pi*r2 = 3.14*82 = 200.96 square inches.
Area = pi*82 = 201.062 square inches rounded to 3 d.p.
area = pi*r2 2r = d r = 8 inches area = pi*82 area = 64pi
Area = 5,281.02 inches2
Area = 5,281.01 feet2
Area of the circle in square inches = pi*82
Area = pi*82 = 201.062 square units to 3 d.p.
Area = pi*82 = which is about 201 square inches to 3 s.f.
A = pi * r2so:A = 3.14 * 82 = 200.96 square meters
