Answer 1

Answer:

40.56 ft

Step-by-step explanation:

The perimeter of a circle is equivalent to $2\pi r$, where r = radius. Therefore, the perimeter of a semicircle should be $\frac{2\pi r}{2}$

In this case, we're given the diameter of the semicircle as 8, so we divide the diameter by 2 and get the radius as 4. Now, let's solve the circumference of the semicircle.

• $\frac{2*3.14*4}{2}$
• $\frac{6.28*4}{2}$
• $\frac{25.12}{2}$
• $12.56$

Now, we're given the lengths of the rectangle as 8, 10, and 10. The perimeter of the rectangle (excluding the inner side) is 28.

28 + 12.56 = 40.56

Therefore, the perimeter is 40.56 ft.
