Final answer:
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.
