Question

A circle has a 10 centimeter radius. Find the area of the circle to the nearest tenth. (Use 3.14 for ?)

Answer 1

314.2 cm^2

Explanation:

The formula for the area of a circle of radius r is A = 3.14r^2.

With r = 10 cm, r^2 = 100 cm^2, and so the area of this circle is 314.2 cm^2, to the nearest tenth.
