He volume V (in cubic feet) of a right cylinder with a height of 5 feet and radius r (in feet) is given by V=5πr2. Solve the formula for r. Then find the radius of the cylinder when the volume is 770 cubic feet. Round your answer to the whole number.

If we divide both sides by we got:

And taking square root we got:

And rounded to the nearest whole number we got 7 ft

Step-by-step explanation:

For this case we know that the hieght of a right cylinder is 5 ft and the volume is given by:

And we know that the volume and we want to solve for r so we can set up the following equation:

If we divide both sides by we got:

And taking square root we got:

And rounded to the nearest whole number we got 7 ft
