What is the area of the composite figure?
(8pi+ 6) in2
(8pi+ 12) in2
(8pi+ 18) in 2
(8pi+ 24) in.2

12+8pi  in^2

Step-by-step explanation:

We have a semicircle with radius of 4

A = 1/2 pi r^2

A = 1/2 pi (4)^2

A = 1/2 (3.14) 16

A = 8pi

We also have a triangle with base (4+4) = 8 and a height 3

A = 1/2 bh

A = 1/2 (8)3

A = 12

Add them together

A = 12+8pi  in^2

the first one, all those points on the line just make a strait line.
