Calculating Volume and Surface Area of Cylinders

What is the formula for the volume of a cylinder?

• V = 2πr(h + r)

• V = πr(h + 2)

• V = 2πr^2 + 2πrh

• V = πr^2h

What does the base area of a cylinder represent?

• The height of the cylinder

• The volume of the cylinder

• The circumference of the cylinder

• The area of the circle forming the base

How do you calculate the surface area of a cylinder?

• SA = 2πr^2 + 2πrh

• SA = 2πr^2 + πrh

• SA = πr(h + 2)

• SA = πr^2 + 2πrh

If a cylinder has a radius of 5 cm and a height of 10 cm, what is its volume?

• 100π cm^3

• 500π cm^3

• 250π cm^3

• 150π cm^3

For a cylinder with a radius of 7 in and a height of 12 in, what is its surface area?

• 266π in^2

• 200π in^2

• 350π in^2

• 150π in^2

Given a cylinder's volume of 324π cm^3 and height of 9 cm, what is its radius?

• 6 cm

• 12 cm

• 9 cm

• 18 cm

What is the surface area of a cylinder with a radius of 6 cm and height of 9 cm?

• 180π cm^2

• 270π cm^2

• 360π cm^2

• 90π cm^2

How do you convert feet to inches for calculating volume in cubic inches?

• Multiply by 3

• Multiply by 12

• Divide by 3

• Divide by 12

What is the volume of a cylinder with a radius of 30 in and height of 14 in?

• 6,300π in^3

• 126π in^3

• 1,260π in^3

• 12,600π in^3

If the radius of a cylinder is given in feet and height in inches, what must you do before calculating the volume?

• Convert the height to feet

• No conversion is necessary

• Convert the radius to inches

• Multiply both measurements by 12
