Question

Consider two circular swimming pools. Pool A has a radius of 38 feet, and Pool B has a diameter of 23.36 meters. Complete the description for which pool has a greater circumference. Round to the nearest hundredth for each circumference. 1 foot ≈ 0.305 meters

Answer 1

Pool B

Explanation:

circumference = 2πr

The radius of a circle is half of the diameter. In order to get both circles in the same equation format, you have to figure out the radius of pool B and convert meters to feet. So, the radius would be 11.68 meters. 11.68 meters divided by 0.305 meters equals 38.3 feet.

pool A -> 2π(38) = 238.76

pool B -> 2π(38.3) = 240.65
