The volume of a cylinder is 200 cubic decimeters, the side area is 100 square centimeters, the radius is? The surface area is?

The volume of a cylinder is 200 cubic decimeters, the side area is 100 square centimeters, the radius is? The surface area is?

Volume of cylinder / side area of cylinder
=πR²H / (2πRH)
=R/2
therefore
The radius of the bottom of the cylinder R
=(200÷100)×2
=2×2
=4 (CM)
Its surface area
=Bottom area × 2 + side area
=3.14×4×4×2+100
=100.48+100
=200.48 (cm2)
