Question

This is math please help me asap

Answer 1

Given :-

• Radius of circle

`\\ \\`

To find:-

• Area of circle

`\\ \\`

Let :

• Area of circle be A.

`\\ \\`

We know:

`\\`

`\bigstar \boxed{ \rm Area \: of \: circle \: = \pi {r}^(2) }`

`\\ \\`

So:-

`\dashrightarrow\sf A= \pi {r}^(2)`

`\\ \\`

`\dashrightarrow\sf A=\pi * {8}^(2)`

`\\ \\`

`\dashrightarrow\sf A= \pi * 8 * 8`

`\\ \\`

`\dashrightarrow\sf A= \pi * 64`

`\\ \\`

`\dashrightarrow\sf A= 64\pi \: ft {}^(2)`

`\\ \\`

Therefore option A is correct
