Area and Volume Formula

What is the formula for the area of a circle?

• = π r ²

• = 1/2 (π r ²⁾

• = 2πr

• = πd

What is the formula for the surface area of a sphere?

• SA = πr²h

• SA = 4πr²

• SA = (4/3)πr²

• SA = (4/3)πr³

What is the formula for the volume of a cone?

• V = (1/3)P*h

• V = (4/3)πr³

• V = πr² + πrl

• V = (1/3)πr²h

What is the formula for the volume of a sphere?

• V = πr²h

• V = 4πr²

• V = (4/3)πr²

• V = (4/3)πr³

What is the formula for volume?

• length x width

• length x width x height

• 1/2 (b x h)

• sum of the lengths of each side

In the volume formula V=lwh, what does the l stand for?

• length

• latitude

• lentils

• large

Find the volume.

• 25 ft³

• 126 ft²

• 126 cubic feet

• 11 cubic feet

What does the "B" in the volume formula?

• Bottom of the object

• Box

• Between

• Area of the base

If the length of a rectangle is tripled and its width is doubled, how does the area change?

• The area is doubled.

• The area is tripled.

• The area is six times larger.

• The area does not change.

Answer explanation

When the length of a rectangle is tripled and its width is doubled, the area becomes 6 times larger because the area of a rectangle is calculated by multiplying its length and width.

Find the volume of a cube with a side length of 5 cm.

• 25 cm³

• 125 cm³

• 75 cm³

• 100 cm³

Answer explanation

To find the volume of a cube, you cube the side length. Volume = side length^3 = 5^3 = 125 cm^3. Therefore, the correct answer is 125 cm^3.
