Question

If the diameter of a penny 19.05 millimeters and the width of each penny is 1.52 millimeters,what is the approximate volume of the roll of pennies?Use 3.14 for and round your answer to the nearest tenth

Answer 1

V = 433.0

Explanation:

Equation for cylinder volume is V = π(radius)²(height)

Find the radius (half of diameter):

19.05 mm / 2 = 9.525 mm

height is 1.52 mm

π = 3.14

V = 3.14 (9.525)² (1.52) = 433.0153

Answer to nearest tenth:

V = 433.0
