Question

Chris is planning to fill up a kiddie swimming pool for

his younger sister but he does not have a water hose. He

has decided to use a cylindrical bucket with a diameter

of 12 inches and a height of 14.5 inches. He has already

calculated the approximate volume of the kiddie pool to

be able to hold about 60,000 cubic inches of water.

Approximately how many buckets of water will he need

to use in order to fill the kiddie pool?

Approximately 9 buckets

B Approximately 115 buckets

© Approximately 37 buckets

0 Approximately 29 buckets

Answer 1

It'll take him approximately 37 buckets.

Explanation:

In order to calculate how many buckets he'll need we first need to calculate the volume of the bucket. Since it's cylindrical it's volume is given by:

bucket volume = pi*r²*h

Where r = d/2 = 12/2 = 6 inches

bucket volume = 3.14*(6)²*14.5 = 45.53*36 = 1639.08 cubic inches

The number of buckets needed is the total volume of the pool divided by the volume of the bucket, so:

buckets = 60000/1639.08 = 36.6 buckets

So it'll take him approximately 37 buckets.
