Answer:
Because the cylinder is open at the top we can either subtract the are of a circle as the topfrom TSA or Add the are with LSA. Here I am subtracting from TSA
Step-by-step explanation:
TSA of a cylinder is 2πr(r+h)
= 2 x 3.14 x 10 (10+14)
= 2 x 3.14 x 10 x 24
= 1507.2 m²
Area of top = Area of circle= πr²
3.14 x 10² = 3.14 x 100
= 314
Therefore surface area of the cylinder =
TSA - area of top = 1507.2 - 314 = 1193.2
