What is the volume of a sphere with a radius of 4.5 inches?
schepotkina [342]

Answer:

D 381.7 in^3

Step-by-step explanation:

V=4/3pi r^3

V=4/3pi 4.5^3

4/3x3.14x4.5x4.5x4.5

It is approximately 381.51 when you use 3.14 as pi. This is closest to answer D, so I would assume it is that.

Sorry, I thought it said circle at first.

26.4 / 1.2 = 22 total boys.


B) Divide total feet by total time:

440 feet / 20 seconds = 22 feet per second.\

Because the submarine is diving the rate would become negative 22 feet per second.
