Answer:
Perimeter = 40.56 inches
Explanation:
The perimeter of a shape is all side lengths added up, so, we know there are sides with the lengths 10 inches, 10 inches, 8 inches, and a semicircle.
To find the perimeter of a semicircle, the formula is
C = πd/2, circumference equals pi times diameter divided by 2 OR C = πr, circumference equals pi times radius.
The diameter is 8, so, filling out the formula, it's
C = 3.14 x 8 /2
C = 25.13/2
C = 12.56
So, adding all the sides up, it's 10 in. + 10 in. + 8 in. + 12.56 in.
Therefore, the answer/perimeter/circumference is 40.56 inches.
This is my second answer so far, I hope it helped!
