Question

Find the total surface area of a solid cylinder whose radius of the base and the height are

14 cm and 10 cm respectively​

Answer 1

$\sf\huge\bold{Solution}$

Given

Radius of Cyclinder is 14 cm ,

and height is 10 cm

To Find

Total surface area of cylinder

=>Total surface area means the total area occupied by Cyclinder including its surface from bottom(base) to the top of the cylinder.

Total surface area or Surface area of Cylinder =2πr(h+r)

=>2×22/7×14(10+14)

=>44/7×14(24)

=>88×24=2112cm²

Total surface area is 2112cm²

Extra information=>

Curved Surface Area = 2πrh

=>2×22/7×14×10

=>44×20=880cm²

Volume of cylinder =πr²h

=>22/7×(14)²×10

=>22/7×196×10

=>22×28×10

=>22×280

=6160cm³
