Review: Surface Area of Prisms and Cylinders

Front

What is the formula for the total surface area of a cylinder?

Back

Total Surface Area = 2πr(h + r), where r is the radius and h is the height.

Front

What is the difference between lateral surface area and total surface area of a cylinder?

Back

Lateral Surface Area = 2πrh; Total Surface Area = Lateral Surface Area + 2πr².

Front

If the radius of a cylinder is doubled, how does the total surface area change?

Back

The total surface area increases by a factor of 4.

Front

What is the formula for the lateral surface area of a prism?

Back

Lateral Surface Area = Perimeter of the base × Height.

Front

How do you calculate the surface area of a rectangular prism?

Back

Surface Area = 2(lw + lh + wh), where l is length, w is width, and h is height.

Front

What is the relationship between the radius and diameter of a circle?

Back

The radius is half of the diameter.

Front

What is the surface area of a cylinder with a radius of 3 inches and a height of 8 inches?

Back

Total Surface Area = 207.35 in².

Front

What units are used to measure surface area?

Back

Square units (e.g., cm², m², in²).

Front

What is the surface area of a cube with a side length of 4 cm?

Back

Surface Area = 96 cm².

Front

How do you find the surface area of a triangular prism?

Back

Surface Area = (Base Area × 2) + (Perimeter of Base × Height).
