What is the total surface area of a cylinder with radius 2cm and height 1.5cm, correct to 2 significant figures?
A
440cm\(^2\)
B
220cm\(^2\)
C
88cm\(^2\)
D
44cm\(^2\)
E
22cm\(^2\)
Verified Correct Answer: D.
Step-by-Step Mathematical Solution
T.S.A of a cylinder = \(2\pi r (r + h)\)
= \(2 \times \frac{22}{7} \times 2 (2 + 1.5)\)
= 44 cm\(^2\)
