The radius of a cylinder is 7 feet. Find the total surface area of the cylinder if the height of the cylinder is 14 feet(in ft²). (Use $\pi =\frac{22}{7}$ )

Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e. 924.

Total Surface Area of Cylinder(TSA) = 2πr(r + h)

Here, r = radius, h height

TSA = 2 × $22\over7$ × 7(7 + 14)

⇒ 44 × 21 = 924 ft²
