The diameter of a cylinder is 14 cm and its height is 9 cm. Find the total surface area of the cylinder.

Correct option is C

Given:
Diameter of the cylinder = 14 cm
Height of the cylinder = 9 cm
π = $$\frac{22}{7}$$​​
Formula used:
Total surface area of a cylinder = 2πr(r + h)
Solution :
Total surface area = 2πr(r + h)
= 2 $$\times \frac{22}{7} \times$$​ 7(7 + 9)
= 44 $$\times$$​ 16
= 704 cm²
