The answer is A
Hope that helps :)
I think it’s this 5x+2= 5x+10
-4x+35=3
Subtract 35 from both sides
-4x=-32
X= 8
<u>Given</u>:
Given that the height of the cone is 12 ft.
The volume of the cone is 90 ft³
We need to determine the area of the base of the cone.
<u>Area of the base of the cone:</u>
The area of the base of the cone can be determined using the formula,
where the base area is
Substituting the value of A in the above formula, we get,
Substituting V = 90 and h = 12, we get;
Dividing both sides by 4, we get;
Thus, the area of the base of the cone is 22.5 square feet.
Hence, Option c is the correct answer.
