Question

Find the volume of a cylinder with a radius of 4 in and a height that is 3 times the radius

Answer 1

602.88 in^3

Explanation:

3.14 * 4^2 * 12

3.14 * 16 * 12

50.24 * 12

(50 * 12) + (0.24 * 12)

600 + 2.88

602.88 in^3

Answer 2

Volume of a cylinder: V = π * r² * h ,

Base surface area of a cylinder: A_b = 2 * π * r² ,

Lateral surface area of a cylinder: A_l = 2 * π * r * h ,

Total surface area of a cylinder: A = A_b + A_l ,

Explanation:

So, when the radius is tripled, the volume will be 3 squared = 9 times than the previous one.
