If a cylinder has a radius of 3 units and a height of 4 units, what is the formula to calculate its surface area?

• Pi*6*4 + Pi*6^2

• 2*pi*3*4 + 2*pi*3^2

• Pi*3*4 + Pi*3^2

• 2*pi*6*4 + 2*pi*6^2

What does the '2' represent in the formula for the surface area of a cylinder (2*pi*r*h + 2*pi*r^2)?

• The two lateral areas

• The height of the cylinder

• The radius of the cylinder

• The two bases of the cylinder

How do you find the radius of a cylinder if you're given the diameter?

• Divide the diameter by 2

• Multiply the diameter by pi

• Divide the diameter by pi

• Multiply the diameter by 2

If the diameter of a cylinder is 10 units, what is the circumference of the base?

• 10*pi units
