Question

A circle has a diameter of 12 inches. what is the area of the shaded section. use 3.14 as pi.

no a,b,c,d just an exact answer thanks

Answer 1

A = pi r ^2
A = 3.14(6^2)
A= 3.14 (36)
A = 113.04

Answer 2

Area of shaded section is 113.04

Explanation:

Area of circle is calculated by formula
`A=\pi r^(2)`.

where 'r' is radius.

here given diameter is 12 inches .

so radius is calculated as
`r=(d)/(2)=(12)/(2)=6`

and value of
`\pi` is 3.14

so, Area is ;

`A=\pi r^(2)`

Put value of
`\pi =3.14` and r=6 inches

`A=3.14*6^(2)`

`A=3.14*36`

`A=113.04`

Hence, area of shaded section is 113.04
