PLZ HELP!!!!!!!!!!!!!!!!

A circle has a diameter of 12 inches.


A circle with a diameter of 12 inches. A triangle with base 12 inches and height 6 inches is cut out of the circle.


What is the area of the shaded sections? Use 3.14 for Pi and round to the nearest hundredth.

77.04

95.04

113.04

149.04

Answer 1

Answer:77.04

Explanation:

A.77.04

B.95.04

C.113.04

D.149.04

Answer 2

`A=77.04\ in^2`

Explanation:

we know that

The area of the shaded sections is equal to the area of the circle minus the area of the triangle

so

`A=\pi r^(2) -(1)/(2)(b)(h)`

where

`r=12/2=6\ in` ----> the radius is half the diameter

`b=12\ in\\h=6\ in`

substitute

`A=(3.14)6^(2) -(1)/(2)(12)(6)`

`A=77.04\ in^2`
