The sphere has a diameter of 15 inches.
What is the approximate volume of the entire sphere?

The answer is 23.55.

Step-by-step explanation:

The volume of a sphere is V=4/3 *pi *r cubed. If you plug in the information into the equation, it will be V=4/3 *pi *7.5 cubed, which gives you the answer 23.55.

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
