Question

Given that the measurement is in centimeters, find the area of the circle to the nearest tenth. (Use 3.14 for π)

A) 28.3 cm2
B) 56.5 cm2
C) 88.7 cm2
D) 254.3 cm2

Answer 1

Option D) 254.3 cm2

Explanation:

we know that

The area of a circle is equal to

`A=\pi r^(2)`

we have

`r=9\ cm`

substitute

`A=(3.14)(9)^(2)=254.3\ cm^2`
