Question

How much ice cream is in a spherical scoop of ice cream with a radius of 3 cm? Use 3.14 as an approximation for pi. Round your answer to the nearest whole number.

Answer 1

So close !


V = (4/3)π 3^3
= 36π
= 113 to the nearest whole number

Answer 2

The volume of a sphere is (4/3)πr^3, so the volume of the scoop of ice cream is (4/3)π(3 cm)^3 = 113.04 cm^3. To convert this to a whole number, round up to 114 cm^3.
