How to find the surface area of a cylinder

The video tutorial explains how to calculate the surface area of a cylinder. It begins by describing the cylinder's structure, including its circular base and height. The teacher then explains the formula for surface area, which involves calculating the area of the base and the area wrapped around the cylinder. The video includes a step-by-step substitution of values into the formula, using a radius of 3 and a height of 7, to find the surface area in square feet.

What is the shape of the base of a cylinder?

• Rectangle

• 12

How do you calculate the surface area of a cylinder?

• Add the area of the base and the height

• Multiply the area of the base by two and add the side area

• Multiply the area of the base by the height

• Add the circumference and the height

What is the formula for the circumference of a circle?

• 2πr

• r^2
