V= pi x r^2 x h
V/(pi x h)=r^2
square root of [V/(pixh)]=r
The answer to question #5 is 17
<u>Given</u> -
- the diameter of a semicircle is 6 yards.
ie. d = 6yd
ps - use 3.14 for a
<u>To find</u> -
- the semicircle's perimeter
<u>Solution</u> -
As we know the formula to find the perimeter of the semicircle is 2r + πr.
But A.T.Q we are only provided with the diameter. As we know that the radius is half of the diameter. ie, r = d/2.
Hence, d = 6
r = 6/2
r = 3 yd
Perimeter of semicircle = 2r + πr
Perimeter of semicircle = 2(3) + 3.14(3)
Perimeter of semicircle = 15.42 yd
<u>Hence forth the semicircle's perimeter is 15.42 yd</u>
