Find the surface area of a cylinder with the following dimensions. use 3.14 for . round to the nearest whole number. r = 6 cm, h = 5 cm a. 517 sq. cm b. 414 sq. cm c. 736 sq. cm d. 298 sq. cm

b. 414 sq cm

The formula for the surface area adds the area of the two circular ends to the lateral area.

... S = 2πr² +2πrh

... = 2πr(r +h)

For r=6 cm, h = 5 cm, the area is ...

... S ≈ 2×3.14×(6 cm)(6 cm+5 cm)

... = 3.14×132 cm²

... ≈ 414 cm²
