Question

I thought I just had to half the diameter and then put it into the volume formula for cylinders but ig I was wrong? Help please?

Answer 1

Answer:

10830.87 mm³

Step-by-step explanation:

Hello!

Volume of a cylinder: $V = \pi r^2(h)$

• $\pi$ = pi
• r = radius (half diameter)
• h = height

The radius for this cylinder is 9.525, after dividing 19.05 by 2.

Plug it into the volume formula to solve for the volume.

Find the Volume

• $V = \pi r^2(h)$
• $V = \pi (9.525)^2(38)$
• $V = \pi (90.725625)(38)$
• $V = 3447.57375\pi$
• $V = 1083087236570...\approx10830.87$

The volume is approximately 10830.87 cubic millimeters.
