Answer 1

The radius of the cheese wheel is 3.5 inches.

To find the radius, we can use the formula for the volume of a cylinder:

V = πr^2h

Plugging in the given values, we get:

155.1 = 3.14 x r^2 x 2.8

Rearranging and solving for r, we get:

r^2 = 155.1 / (3.14 x 2.8)

r^2 ≈ 14.81

r ≈ √14.81

r ≈ 3.5

Therefore, the radius of the cheese wheel is approximately 3.5 inches.
