Volume of Cylinders

Front

What is the formula for the volume of a cylinder?

Back

Volume = π × r² × h, where r is the radius and h is the height.

Front

What does 'π' represent in the volume formula?

Back

π (pi) is a mathematical constant approximately equal to 3.14, representing the ratio of the circumference of a circle to its diameter.

Front

If a cylinder has a radius of 3 cm and a height of 10 cm, what is its volume?

Back

Volume = π × (3 cm)² × (10 cm) = 94.2 cm³ (rounded to the nearest tenth).

Front

How do you convert the volume from cubic centimeters to cubic inches?

Back

1 cm³ = 0.0610237 in³. Multiply the volume in cm³ by 0.0610237 to convert to in³.

Front

What is the volume of a cylinder with a radius of 4 inches and a height of 5 inches?

Back

Volume = π × (4 in)² × (5 in) = 62.8 in³ (rounded to the nearest tenth).

Front

What is the significance of the height in the volume of a cylinder?

Back

The height determines how tall the cylinder is, affecting the total volume of space it occupies.

Front

If a cylinder is filled to half its height, how does that affect its volume?

Back

The volume is halved since volume is directly proportional to height.

Front

What is the volume of a cylinder with a radius of 7 cm and a height of 12 cm?

Back

Volume = π × (7 cm)² × (12 cm) = 1,384.0 cm³ (rounded to the nearest tenth).

Front

How do you find the radius if you know the volume and height of a cylinder?

Back

Rearrange the volume formula: r = √(Volume / (π × h)).

Front

What is the volume of a cylinder with a radius of 5 cm and a height of 15 cm?

Back

Volume = π × (5 cm)² × (15 cm) = 392.7 cm³ (rounded to the nearest tenth).
