Surface Area

Question 14 • Mathematical Models with Applications - MA4072 CR

What is the surface area of a cylinder with the given dimensions? Express your answer to nearest hundredth. Use 3.14 for pi.Radius = 9 cm.; Height = 6 cm.

Answer
A
982.45 sq. cm
B
1281.34 sq.cm
C
876.34 sq.cm
D
847.80 sq. cm

Explanation

The total surface area of a cylinder is 2πr² + 2πrh. Substituting r = 9 cm, h = 6 cm, and π = 3.14 gives 2(3.14)(9²) + 2(3.14)(9)(6) = 508.68 + 339.12 = 847.80 square centimeters. The correct choice is 847.80 sq. cm.
