Help Please!

Hello,
I have been at a standstill for two days now. I am not good at math and need help badly. There are two questions I simply cannot figure out, they are: 1. What alternative answer is equal to 5.59? And...

2. What is the volume of a sphere with a radius of 4.5 inches?


I am stuck

Stop saying that. It is a self-fulfilling prophecy.

1. What alternative answer is equal to 5.59?

Wow, that's a tough one. A better description of the problem might help.

5 + 59/100?

Five and fifty-nine hundreths?

2. What is the volume of a sphere with a radius of 4.5 inches?

Sphere Volume = (4/3)*pi*r³ = (4/3)*pi*(4.5 in)³ = apprx 381.7 in³ = apprx 0.2209 ft³
