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:

<u>The volume formula:</u>

  • V = πr²h

<u>Given:</u>

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

<u>The volume of each penny:</u>

  • V = π(0.75/2)²(0.04)

<u>The volume of 100 pennies:</u>

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

Correct choice is B
