What is the effect of increasing the height of a cone on its volume?

• Increasing the height of a cone increases its volume linearly; if height doubles, volume also doubles.

• Increasing the height of a cone has no effect on its volume.

• Increasing the height of a cone decreases its volume.

• The volume of a cone increases exponentially with height.

How do you round a number to the nearest tenth?

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

• Always round up regardless of the hundredths place.

• Round down if the number is odd, and round up if it's even.

• Ignore the hundredths place and keep the tenths as is.

How do you calculate the volume of a cone using 3.14 for π?

• Volume = (1/3) × 3.14 × r² × h

• Volume = 3.14 × r × h

• Volume = (1/2) × 3.14 × r² × h

• Volume = 3.14 × r² × h

What is the formula for the volume of a cone?

• Volume = (1/3) × π × r² × h, where r is the radius and h is the height.

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

• Volume = (2/3) × π × r² × h, where r is the radius and h is the height.

• Volume = (1/4) × π × r² × h, where r is the radius and h is the height.
