Question

:((( can someone help mee with this

Answer 1

40.56 ft

Explanation:

The perimeter of a circle is equivalent to
`2\pi r`, where r = radius. Therefore, the perimeter of a semicircle should be
`(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.

• 
  `(2*3.14*4)/(2)`
• 
  `(6.28*4)/(2)`
• 
  `(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.
