A softball has a circumference of 12 inches. What is the softball's approximate volume? A. 16.41 in.^3 B. 24.56 in.^3 C. 29.18 in.^3 or D. 31.27 in.^3

C. 29.18 in.^3

Step-by-step explanation:

step 1

Find the radius of the softball

The circumference is equal to

substitute the given values

solve for r

step 2

Find the volume

The volume of the sphere is equal to

substitute

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
