Question

What is the approximate area of the circle shown below? (The radius is 21cm)

A. 1385 cm2
B. 66 cm2
C. 5540 cm2
D. 132 cm

Answer 1

A. 1385 cm²

Explanation:

Area of a circle is πr²

We know what the radius is, so all we have to do is plug it in.

π(21)²

π(21)²= 1385.44

Since it's approximate, it would just be 1385 cm²

Answer 2

The answer is A. 1385 cm2

Explanation:

Use the formula A = pi times radius squared
