Question

What is the approximate area of the following circle?

Answer 1

Answer: 38.47 m^2

work is shown in picture :)

Answer 2

`38.47 {m}^(2)`

Explanation:

The formula to find the area of a circle is

`a= \pi {r}^(2)`

We know that

`\pi = 3.14 \: \: \: \: \: \: r = 3.5`

Therefore the area is

`a= \pi {r}^(2) \\ \\ a = (3.14) {(3.5)}^(2) \\ \\ a = 3.14 * 12.25 \\ \\ a = 38.47 {m}^(2)`
