Question

A family is filling up a circular pool. The pool has a depth of 6 feet and a diameter of 8 feet. If there are approximately 7.48 gallons of water in a cubic foot, how many gallons of water will it take to fill up the pool completely? Use π = 3.14 and round to the nearest gallon.

2,255 gallons
1,127 gallons
301 gallons
40 gallons

Answer 1

V circular pool : π*4²*6≈301,44feet³

gallons of water

7,48gallons (7,48*301,44)/1=2254,7712=2255gallons

1feet³ 301,44feet³

Explanation:

Answer 2

Explanation:

radius = 1/2 of the diameter = 1/2 of 8 = 4

Volume = π r² h

v = 3.14 × 4² × 6

v = 3.14 × 16 × 6

v = 301.44 cu ft²

Then mulitply the volume by 7.48

to find the gallons of water in the pool.

301.44 × 7.48 = 2254.771

rounded to 2255 gallons
