Question

What is the area of a 3 and a quarter inch circle?

Answer 1

33.2in²

Explanation:

to find area we have to find redious first so

• r=d/2

therefore

`r = (3 (1)/(4) )/(2)`

`r = ( (13)/(2) )/(2)`

`r = (13)/(2) / 2`

`r = (13)/(4)`

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

`= \pi ((13)/(4) ) ^(2) i {n}^(2)`

`= \pi * (169)/(16) {in}^(2)`

`= (169\pi)/(16) i {n}^(2)`

`= 33.2 \: i {n}^(2)`
