Question

ind the surface area of a cylinder with a height of 8 inches and a base diameter of 6 inches use 3.14

Answer 1

The surface area of the cylinder with the given height and base diameter is 207.24in².

What is the surface area of the cylinder?

The surface area of a cylinder is expressed mathematically as;

S.A = 2πrh + 2πr²

Given the data in the question;

• Height h = 8in
• Diameter d = 6in
• Radius = d/2 = 6/2 = 3in
• Constant pi π = 3.14
• Surface area S.A = ?

We plug the given values into the equation above.

S.A = 2πrh + 2πr²

S.A = ( 2 × 3.14 × 3in × 8in ) + ( 2 × 3.14  × (3in)² )

S.A = 150.72in² + 56.52in²

S.A = 207.24in²

Therefore, the surface area of the cylinder with the given height and base diameter is 207.24in².
