Question
Solution 1
The surface area of a right cylinder is given by the formula: 2πrh + 2πr²
Where: r = radius of the base of the cylinder h = height of the cylinder
Given: r = 4 units h = 11 units
Substitute these values into the formula:
Surface area = 2π(4)(11) + 2π(4)² = 88π + 32π = 120π units²
