Volume and Surface Area Test 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.

Front

How do you find the radius of a cylinder if you know the diameter?

Back

Radius = Diameter / 2.

Front

What is the formula for the volume of a cylinder?

Back

Volume = πr²h, where r is the radius and h is the height.

Front

If the height of a cylinder is 10 ft and the diameter is 6 ft, what is the radius?

Back

Radius = 6 ft / 2 = 3 ft.

Front

What is the value of π used in calculations?

Back

Use 3.14 for π in calculations unless otherwise specified.

Front

How do you calculate the surface area of a cylinder with a height of 10 ft and a radius of 3 ft?

Back

Surface Area = 2π(3)(10 + 3) = 2π(3)(13) = 78π ft².

Front

What is the surface area of a cylinder with a radius of 6.4 inches and a height of 10 inches?

Back

Surface Area = 2π(6.4)(10 + 6.4) = 2π(6.4)(16.4) = 209.92π in².

Front

What is the volume of a cylinder with a radius of 3 ft and a height of 10 ft?

Back

Volume = π(3)²(10) = 90π ft³.

Front

How do you round a number to the nearest tenth?

Back

Look at the hundredths place; if it's 5 or more, round up.

Front

What is the surface area of a water tank with a height of 10 ft and a diameter of 6 ft?

Back

Surface Area = 2πr(h + r) = 2π(3)(10 + 3) = 78π ft².
