Surface Area

Question 3 • 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 = 8 cm.; Height = 12 cm.

Answer
A
980.45 sq. cm
B
1280.34 sq.cm
C
876.34 sq.cm
D
1004.80 sq. cm

Explanation

The total surface area of a cylinder is 2πr² + 2πrh. With radius 8 cm and height 12 cm, this is 2(3.14)(8²) + 2(3.14)(8)(12) = 401.92 + 602.88 = 1004.80 square centimeters. The correct choice is D, 1004.80 sq. cm.
