Answer:

ok, so write down equation for circumference first, substituting pi symbol with 3.14, and substitute 8 for diameter, because the diameter of the circle and the height of rectangle is the same.

C=3.14×8

C=25.12

then you divide it by 2 because it's only half a circle.

25.12÷2=12.56

Next you find the perimeter of the rectangle

(10×2)+8=28

you dont add the right side,8, because that's where the half circle is. Now you add the half circle and the perimeter of the rectangle.

28+12.56=40.56

and then round to the nearest hundredth
