Question

A kiddie pool has a diameter of 4 ft and a height of 2 ft. About how many gallons are in the pool? For simplicity, assume π is 3, and a gallon is 0.1 cubic feet.

a) 6.67 gallons
b) 16.67 gallons
c) 26.67 gallons
d) 36.67 gallons

Answer 1

The volume of the kiddie pool is calculated using the formula V = πr^2h. Plugging in the values, we find that the pool holds approximately 2.4 gallons.

Step-by-step explanation:

To find the number of gallons in the kiddie pool, we need to calculate the volume of the pool first. The formula to calculate the volume of a cylinder is V = πr^2h, where V is the volume, π is the approximate value of pi, r is the radius (half the diameter), and h is the height.

Given that the diameter of the pool is 4 ft, the radius would be 2 ft (half of 4 ft), and the height is 2 ft.

Plugging the values into the formula, V = 3 * 2^2 * 2 = 24 cubic feet.

Since 1 gallon is equivalent to 0.1 cubic feet, the number of gallons in the pool would be 24 * 0.1 = 2.4 gallons.

Therefore, the closest option to the estimated number of gallons in the pool is c) 26.67 gallons.
