Question

Calculate the area of each circle

Answer 1

Answer:

$2.01 \: {inches}^{2}$

Step-by-step 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;

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