Question

The diameter of the circle below measures 7 cm,

What is the approximate area of the circle?
A. 14 cm2
B. 22 cm2
C. 38 cm2
D. 154 cm2

Answer 1

Answer: D

Explanation:

Remember the formula -

`A = \pi` ×
`r^(2)`

π = 3.14

`r^(2)` = 7

7² = 49

3.14 x 49 = 153.94

A = π · r² = π · 72 ≈ 153.93804

153.93804 ⇒ 154 (rounded)

Your answer is D.
