#r=1.53# #\text{inches}# is the required radius of sphere rouded to the nearest hundredth.

In the given formula, we need to put the value of volume, so by putting, we will get:

#15 \text{in}^3 = 4/3\pi r^3#

Put the value of #\pi=3.14# and we will have:

#15 \text{in}^3 = 4/3(3.14) r^3#

Solve the equation for #r#, so that we have:

#r^3={15\times3}/{4\times3.14}#

Taking cube root, we have:

#r=1.53# # ##\text{inches}#
