Answer:
924 m²
Step-by-step explanation:
Given -
Radius of cylinder (r) = 7 m
Height of cylinder (h) = 14 m
To find -
T. S. A. (Total Surface Area) of cylinder
Solution -
T. S. A. of cylinder = 2πr (h + r)
Hence T. S. A. of cylinder =924 m²
Mote to know :-
T. S. A of cylinder = 2πr (h+r)
C. S. A of cylinder = 2πrh
Volume of cylinder = πr²h
We can also prove these formulas by opening the cylinder into rectangle. And in the rectangle the breadth will be circumference of base and length will be height.
hope it helps.
