## bmar1209 Help Needed! Find the area of each of the following shaded parts. Assume all arcs are circular. Leave all answers in terms of pi. one year ago one year ago

1. bmar1209

2. campbell_st

the area of the large semi-circle is $A = 1/2 \pi r^2$ the 2 small semi-circles has the same radius r/2 and combined have the area of a whole circle $A=\pi (r/2)^2 = 1/4 \pi r^2$

3. myko

Are of each part is: $1/2(1/2\pi r ^{2})$

4. bmar1209

So would the answer be $A= 1/4\pi r ^{2}$ ?

5. myko

yes

6. campbell_st

the green shaded area is A = 1/4 pi r^2 that appears to be the only area you need to find

7. bmar1209

yes, just the shaded portion. Thank you both for helping me!
