Answer: 36.84
(lmk if this isnt right)
Step-by-step explanation:
To find the perimeter of the rectangle:
3+3+3+3+3+3=18
or
3(6)=18
To find the diameter of the circle:
12-(3+3)
12-6=6
You can combine the 2 half circles to make 1 full circle since they both have the same diameter. Use the circumference formula to solve.
C=πd
Substitute
C=3.14(6)
Multiply
C=18.84
Add the perimeter of the rectangle and the circumference of the circle.
18+18.84=36.84
