Answer:
490.9 square feet.
Step-by-step explanation:
We have been given that a contractor is building the base of a circular fountain. The base of the fountain has a diameter of 25 feet. We are asked to find the area of the base of the fountain.
We will use area of circle formula to solve our given problem.
, where r represents radius of circle.
We know that diameter is 2 times radius, so radius of the base of fountain would be half the diameter.




Upon rounding our answer to nearest tenth, we will get:

Therefore, the area of the base of the fountain would be 490.9 square feet.
Answer:
x = 126
Step-by-step explanation:
The angles are complementary which means they sum to 180
x+54 =180
x = 180-54
x = 126
Tanisha: She simplified the X and Y so they will only appear on one side.
Neal: He took away the parentheses so that he could put the exponent elsewhere.
They both are doing the problem right, just in completely different ways.
