Please i need help on my math
Kamila [148]

Answer:

V = \pi (2.5)^2h

Step-by-step explanation:

The formula for the volume of a cylinder, is V = π r^2 h. It shows that the diameter is 5. But we need the radius. The radius is half of the diameter. So, 5/2. This gets you 2.5.

The equation is now:

V = π(2.5)^2h

This is the answer.

V = \pi (2.5)^2h
