Unit 7 Test Review

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

How do you calculate the density of a substance?

Back

Density = mass/volume.

Front

What is the volume of a sphere with a radius of 1 cm?

Back

Volume = (4/3)πr³ = 4.18 cm³.

Front

What is the formula for the volume of a cone?

Back

Volume = (1/3)πr²h, where r is the radius and h is the height.

Front

If a prism has a base area of 10 cm² and a height of 5 cm, what is its volume?

Back

Volume = base area × height = 10 cm² × 5 cm = 50 cm³.

Front

What is the relationship between volume and capacity?

Back

Volume is the amount of space an object occupies, while capacity is the maximum amount a container can hold.

Front

What is the formula for the volume of a rectangular prism?

Back

Volume = length × width × height.

Front

How do you find the missing length of a prism if you know the volume and the other dimensions?

Back

Missing length = Volume / (width × height).

Front

What is the volume of a cylinder with a diameter of 18 cm and a height of 25 cm?

Back

Volume = πr²h = π(9 cm)²(25 cm) ≈ 2119.5 cm³.

Front

What is the significance of units in volume calculations?

Back

Units must be consistent; for example, all measurements should be in cm or m.
