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

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
