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!

Have a great day
Five less than twice what negative number squared is 157 <- put into an expression
-5 + 2(-x^2) = 157
Now simplify:
-5 + -2x^2 = 157
-2x^2 = 162
-2x^2 - 162 = 0
2x^2 + 162 = 0
x^2 + 81 = 0
