What is the area of a circle with a radius of 8 centimeters?

Answer 1

The formula for finding the area of a circle is A = Pi x R² where Pi = 3.1416 and R² is the radius multiplied by itself. Using the formula, A = 3.1416 x (8 x 8) = 3.1416 x 64 = 201.0624 sq cm

Answer 2

16 pi cm (exactly)

50.26 cm (correct to 2 decimal places)

50.27 cm (rounded to 2 decimal places)

Answer 3

A radius (not raduis) of 8 cm implies an area of 201 sq cm.

Answer 4

Area = pi*r2 = 201.1 cm2
