Question

PLease help me i promise ill follow you and mark you brainlist i just really need help

Answer 1

1) Radius = 10 inches

So,

$Area = \pi {r}^{2} \\ = > 3.14 \times {(10)}^{2} \\ = > 3.14 \times 100 \\ = > \pink{ 314.0 \: \: \rm {inches}^{2} }$

2) Radius = 2 ft

So,

$Area = \pi {r}^{2} \\ = > 3.14 \times {(2)}^{2} \\ = > 3.14 \times 4 \\ = > \pink{ 12.56 \: \: \rm {ft}^{2} }\\ = > 12.5 \: \: \rm{ft}^{2}$

3) Radius = 10 cm

So,

$Area = \pi{r}^{2} \\ = > 3.14 \times {(10)}^{2} \\ = > 3.14 \times 100 \\ = > \pink{314.0 \: \: \rm{cm}^{2} }$
