The volume of a sphere is found from the equation V=4/3πr
r is the radius.
If the radius is 45 cm and pi is about 3.14, you can rewrite and equation as V=4/3(3.14)(45)
Then just solve by multiplying all the terms!
4/3(3.14) = 4.19
4.19(45) = 188.55
So the volume of the ball is 188.55 cm cubed.
10,000,000+2,000,000+
400,000+30,000+90
The wrong step is step 4, because you only need one conversion.
The formula to convers pounds to kilograms is

Obviously, the inverse formula is

So, you're given an input of 142 pounds. To convert it in kilograms, plug that value into out formula:

and this is the answer you're looking for, so you need no more steps.
