You have the right answer I think!!
Well they are similar by ASA
30/25=1.2
20*1.2=24
24=4x-4
28=4x
7=x
Answer:
59.67 rounds to 60, 11.1 rounds to 10, so 60 divided y 10 equals 6
Step-by-step explanation:

<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>
