Try to get x by itself
so minus 8 from both sides
you end up with 5x^2=125
answer is 3rd option
Answer: The height of the cylinder is 24 units.
Step-by-step-explanation: The volume of a cylinder is calculated as
Volume = Pi x r^2 x h
Where r is the radius, and h is the height. The radius shall be derived as half of the diameter, that is, half of 14 units which equals 7 units. The volume has been given as 1176 Pi cubic units. We can now substitute for the values given as follows;
1176 Pi = Pi x 7^2 x h
1176 Pi = Pi x 49 x h
By cross multiplication we now have
(1176 Pi)/49 Pi = h
1176/49 = h
24 = h
Therefore the height of the cylinder is 24 units.
12.325-(2.34x3.9)
12.325-(9.126)
3.199 ~3.2

We have been given that a sphere and a cylinder have the same radius and height. The volume of the cylinder is 21 meters cubed. We are asked to find the volume of the sphere.
We know that height of sphere is equal to its radius. This means that 
.
Using , we will get:
Upon comparing volume of sphere and volume of cylinder, we can see that volume of sphere is 
times volume of cylinder.
Therefore, the volume of the sphere would be 28 cubic meters.
