Question

Calculate the area of each circle

Answer 1

`2.01 \: {inches}^(2)`

Explanation:

The formula to find the area of a circle is

`area \: of \: circle \: = \pi {r}^(2)`

Let pi be (3.14), the radios as given in the question is (1.6 ÷ 2 = 0.8). Therefore;

`\pi {r}^(2) = \\ (3.14) \: {(0.8)}^(2) \\ 3.14 * 0.64 = \\ 2.0096\: or \: 2.01{inches}^(2)`
