The diameter of the base of a right circular cylinder is 14 cm, while its length is 40 cm. Find the total surface area of the cylinder.
Correct Answer: Description for Correct answer:
Total surface area of cylinder
= \( \Large 2 \pi r \left(h + r\right) \)
Given that, \( \Large r = \frac{14}{2} \) = 7 cm, h = 40 cm
Therefore, Required total surface area
= \( \Large 2 \times \frac{22}{7} \times 7 \times \left(40 + 7\right) \)
= \( \Large 44 \times 47 = 2068 sq. cm. \)
