Question 29 • 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.Diameter = 14cm.; Height = 6 cm.

Answer
A
582.45 sq. cm
B
581.34 sq.cm
C
571.48 sq.cm
D
547.80 sq. cm

Explanation

The cylinder’s radius is half its 14 cm diameter, so r = 7 cm. Use the total surface area formula, 2πr² + 2πrh: 2(3.14)(7²) + 2(3.14)(7)(6) = 307.72 + 263.76 = 571.48 square centimeters. The correct choice is 571.48 sq. cm.
