A cylinder has a height of 1 m and the circumference of its base is 176 cm. How many sq cm is its total surface area?
Let the base radius be ‘r’ and height be ‘h’ and diameter be ‘d’
⇒ Given that circumference of base C = 176 cm
C=2 π× r=176 cm
r=28cm
and h = 1m=100cm
⇒ Curved surface area A1= Circumference* height
The Surface area at top and bottom are
Total surface area A=Curved surface area + Area at top and bottom
A=A1 + A2
A=17600 + 4928
Total surface area 
Ans. 22528 sq cm
