The surface area of a cylinder that the radius tripled and it height is brought down to half is 3890.46 inches²

<h3 /><h3>How to find the surface area of a cylinder?</h3>

Surface area of a cylinder = 2πr(r + h)

Therefore,

radius is tripled = 3(7) = 21 inches

height is shrunk half its size = 17 / 2 = 8.5 inches

Therefore,

surface area = 2 × 3.14 × 21 (21 + 8.5)

surface area = 131.88(29.5)

surface area = 3890.46 inches²
