Exercise 20 Page 852

The volume of a sphere is four-thirds the product of π and the cube of the radius.

11.5yd^3

Practice makes perfect

The volume of a sphere is four-thirds the product of π and the cube of the radius. V=4/3π r^3 We are given that the radius is 1.4yards. Therefore, we can substitute 1.4 for r in the above formula and simplify the right-hand side.

V=4/3π r^3

Substitute

r= 1.4

V=4/3π ( 1.4)^3
