Surface Area Review

Front

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

Back

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

What is the surface area of a sphere with radius r?

Back

Surface Area = 4πr².

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.

What is the surface area of a cone with radius r and height h?

Back

Surface Area = πr(r + √(h² + r²)).

Front

How do you find the surface area of a composite shape?

Back

Calculate the surface area of each individual shape and then sum them up.

What is the surface area of a rectangular brick with dimensions 5 cm x 9 cm x 20 cm?

Back

Surface Area = 650 cm².

Front

What is the relationship between surface area and volume?

Back

Surface area measures the total area of the surface of a three-dimensional object, while volume measures the space inside it.
