Answer:
Hi there!
The correct answer is: 220.5 cm²
Step-by-step explanation:
This is an example of a composite figure where you have to break up the figure into different shapes. In this case this figure, can break up into a semicircle and a triangle.
Triangle: A= 1/2bh A=1/2(16)(15) = 120 cm²
Semicircle: another way of saying half a circle so A= 1/2 πr²
A=(1/2)(π)(8)² = 100.5 cm²
And then you just add the two areas together and you get 220.53 cm²
