The volume of a sphere is 4,000π m3. what is the diameter of the sphere to the nearest meter?

diameter = 29 m

Step-by-step explanation:

Given that:

volume of a sphere = 4,000π m3.

WE know that:

volume of a sphere = 4/3 πr^3

So equating both equations:

4/3 πr^3 =  4,000π m3.

Multiplying both sides by 3/4

πr^3 =  3/4*4,000π m3.

πr^3 =  3/4*4,000π m3.

πr^3 =  3,000π m3.

Dividing both sides by π

r^3 =  3,000 m3.

Taking cube root on both sides

r = 14.38 m

For finding diameter:

diameter = r * 2

diameter = 28.768 m

By rounding off:

diameter = 29 m

 3.6×10^8

Step-by-step explanation:

Your calculator or spreadsheet can multiply these numbers for you and give you the answer in scientific notation.

  (3.1×10^3)×(1.148×10^5) = (3.1×1.148)×10^(3+5) = 3.5588×10^8

The supplied numbers have 2 and 4 significant digits, so rounding of the answer to 2 significant digits is appropriate.
