A roll of 100 pennies is in the shape of a right cylinder. Each penny has a diameter of 0.75 inches and a thickness of 0.04 inch

zalisa [80]

Answer:

(B) π(0.75/2)²(4)

Step-by-step explanation:

The volume formula:

V = πr²h

Given:

d = 0.75 in ⇒ r = d/2 = 0.75/2 in
h = 0.04 in

The volume of each penny:

V = π(0.75/2)²(0.04)

The volume of 100 pennies:

V = 100*π(0.75/2)²(0.04) = π(0.75/2)²(4)

Correct choice is B
