Sara goes on a slingshot ride in an amusement park. She is strapped into a spherical ball that has a radius of 3*10^2 centimeters. What is the volume of air in the spherical ball? Use this formula: volume of a sphere = 4/3πr^3, where r is the sphere’s radius.

A. 4*π*3^2*10^6 cm^3

B. 4*π*3^3*10^6 cm^3

C. 4*π*3^2*10^5 cm^3

D. 4*π*3^4*10^5 cm^3

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
