Volume of Cylinders

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

Back

Radius = Diameter / 2.

Front

What is the value of π (pi) commonly used in calculations?

Back

3.14.

Front

If a cylinder has a height of 10 cm and a radius of 2 cm, what is its volume?

Back

Volume = π(2)²(10) = 40π ≈ 125.6 cm³.

Front

What is the volume of a cylinder with a diameter of 6 cm and a height of 5 cm?

Back

Volume = π(3)²(5) = 45π ≈ 141.4 cm³.

Front

How do you round a number to the nearest tenths?

Back

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

Front

What is the volume of a cylinder with a diameter of 4 m and a height of 3 m?

Back

Volume = π(2)²(3) = 12π ≈ 37.7 m³.

Front

If a cylindrical container has a radius of 5 inches and a height of 10 inches, what is its volume?

Back

Volume = π(5)²(10) = 250π ≈ 785.4 in³.

Front

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

Back

The diameter is twice the radius.

Front

How do you calculate the volume of a cylinder using a calculator?

Back

Input the formula: π * (radius^2) * height.
