Exercise 3 Page 458

Consider the given sphere.

To calculate the volume of a sphere, we can use the formula where r is the radius. V=4/3π r^3 We can see that the diameter is 26feet. We get the radius of the circle by dividing by 2. r=26/2= 13ft We can calculate V by substituting r with 13 in the formula.

V=4/3π r^3

Substitute

r= 13

V=4/3π ( 13)^3
