Answer:
It is given that the volume of a cone =
cubic units
Volume of cone with radius 'r' and height 'h' = 
Equating the given volumes, we get

× 

It is given that the height is 'x' units.
Therefore, 

Therefore, 
So, the expression '
' represents the radius of the cone's base in units.
He needed to divide instead of subtracting it on the last step.
It is zero
the answer is 5.3 x 10^0
because 10^1 would force you to move the decimal place to make it 53
I hope this helps!
