**A cylinder has the base area of 616 cm square. Find its radius.**

area = 616

radius = sqrt( 616 / PI )

radius = 14

diameter = 14 * 2

diameter = 28

radius = 28 / 2

A cylinder is a closed solid that has two parallel (usually circular) bases connected by a curved surface.

where,

d = diameter

A = area

C = circumference

r = radius

V = volume

CSA = curved surface area

TSA = total surface area

BSA = base surface area

density = density

m = mass

h = height

u = unit
