What is the surface area formula for a cylinder?

•  πrh + πr²

• = 2πrh + 2πr²

• = 4πr²

•  πr²

Campbell Soup is creating a new soup label. If a can has a height of 6 in and a diameter of 4 in, how much material does Campbell need for each soup label? Which formula can be used to find the surface area of the label?

• SA=2πrh+2r²

• SA=2πrh

• SA=Ph+2B

• V=Bh

Answer explanation

This is a triangular prism, the base is a triangle, not the rectangle!

Area of the triangle is bh/2 so 2(2)/2=2, Perimeter of the base is the distance around the triangle, 2+2+2.8 = 6.8, and height is the distance between the two bases, 5. So,

SA = 2B + Ph

SA = 2(2)+6.8(5)

SA = 38

V = Bh

V = 2(5)

V = 10
