Answer:
17662.5 sq. feet
Step-by-step explanation:
We know that the formula for Area of a Circle is
.
r = radius; d = diameter, which is r*2
And so, in the question, it gives you that the diameter is 150, first we divide it by 2 to get the radius.
150/2 = 75
The question said to keep
=3.14, so then we plug in the equation-

Then we use PEMDAS [Parenthesis; Exponents; Multiply & Divide; Add & Subtract] which would get us-
(first doing the Exponent)
And we continue-
(then multiple)
So our answer is-
17662.5 sq. feet
I hope this helps!
Please give brainliest!
Have a great day

Answer:
Step-by-step explanation:
Surface area is the sum of areas of 4 triangles.
<u>Each triangle has:</u>
<u>Area of each triangle:</u>
- A = 1/2bh
- A = 1/2*9*7.79 = 35.055 ft²
<u>Surface area:</u>
- S = 4*35.055 = 140.22 ft²
