6 pounds cost $13.80
1 pound will cost $13.80/6
2.5 pounds will then cost 13.80/6 * 2.5 = $5.75
$5.75
Multiply the volume by 3. For example, suppose the volume of the sphere is 100 cubic units. Multiplying that amount by 3 equals 300.
Divide this figure by 4π. In this example, dividing 300 by 4π gives a quotient of 23.873.
Calculate the cube root of that number. For this example, the cube root of 23.873 equals 2.879. The radius is 2.879 units.
