Question

A closed circular cylinder has diameter 20 cm and height 30 cm. Find the total surface area of the cylinder. (π=3.14)​

Answer 1

Hey!!!

Here's your answer

Total surface area of cylinder

=2πR(R+H)

We have,

R= 20/2= 10cm

H= 30 cm

π= 3.14

By applying the formula, we get

Total surface area= 2×3.14×10(10+30)

=6.28×10(40)

=6.28×400

=2512 cm^2
