**Answer:**

In mathematics, the Pythagorean theorem, also known as Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

**Step-by-step explanation:**

a^2 plus b^2=c^2

**Answer:**

The answer is 576 seats

**Step-by-step explanation:**

3 rows x 12 seats = 36 seats in one section

36 seats in one section x 16 sections = 576 seats

Volume of a cylinder= π r² h

r= 5ft

h= 15ft

V= π (5²)(15)

V= π(25)(15)

V= 375π ft³ ≈ 1178.10 ft³

**Answer:**

The volume is about 1178.10 cubic feet.

**Answer: C: 43**

**Step-by-step explanation:**

As we are calling the function with 2 for x, we can substitute 2 for every x we see in the function and solve.

Hence, f(2) is **43**.
