Given the cross sectional area, CSA, of a cylinder to be
The cross section of a cylinder is a circle, thus the formula for the cross sectional area of a cylinder is
Solving to find the radius of the cylinder below
To find the total surface area, TSA, of a cylinder, the formula is
Where
Subsitute the values intom the formula for the total surface area of a cylinder
Hence, the total surface area of the cylinder is 565.3cm² (nearest tenth)
