and a diameter of 1
__

4 ft to scoop water from the

(b)
What is the exact volume of the cup?
(c)
How many full cups of water can Angelica
get from the container

Answers

Given:
large cylinder: height = 3 ft ; diameter = 2 ft
cylinrical cup: height = 1/2 ft ; diameter = 1/4 ft

Volume of a cylinder = π r² h

large cylinder volume = 3.14 * (1ft)² * 3ft = 3.14 * 1ft² * 3ft = 9.42 ft³

cylindrical cup volume = 3.14 * (0.125ft)² * 1/2 ft = 3.14 * 0.015625ft² * 0.5ft =  0.0245 ft³

9.42 ft³ ÷ 0.0245ft³ = 384.489 cups
