The a company is selling two different sized medicine balls to a local college's athletic department. ratio of the diameters is 15: 11. if the diameter of the smaller ball is 55 cm, what is the volume of the larger ball?

Volume of the larger ball = 220893.233 cm^3

Step-by-step explanation:

The ratio of the diameter is

r = 15/11

r = larger diameter / smaller diameter

r = larger diameter/ 55 cm

larger diameter = r*55 cm

larger diameter = 75 cm

larger radius = larger diameter/2 =   37.5 cm

Volume of the ball = (4/3)*π*radius^(3)

Volume of the ball = (4/3)*π*(37.5 cm)^(3)

Volume of the larger ball = 220893.233 cm^3

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
