Answer:

Explanation:

radius r of cylinder = 7

circumference of cylinder = 2πr = 14π meters.

lateral area of cylinder = 14π×11 = 154π m². This is represented by the rectangle.

area of top = πr² = 49π m²

area of bottom = area of top = 49π m²

total surface area = lateral area + 2(top area) = 154π + 2×49π = 252π ≅ 792 m²
