Answer:
1. Area = Base * Height
2. 144x = 4x * 4x
3. 144x = 16(x^2)
4. 9x = x^2
5. x = 9

Answer:
A
Step-by-step explanation:
The volume (V) of a pyramid is
V =
area of base × perpendicular height (h)
area of square base = 4² = 16 and h = 4, hence
V =
× 16 × 4 =
= 21
ft³
Step-by-step explanation:
The volume of a cylinder can be found with the equation
<em><u>
</u></em>
So, plug in the values. The diameter of the circle is 10m, which means that the radius is 5m. The height of the cylinder is 13m.
V = π (5)^2 (13)
<u>V = 325π m^3</u>
Answer:
D. 325π m^3
