Question

The diameter of a cylinder is 28cm and its height is 20cm.
Find
the total surface area of the cylinder.​

Answer 1

Answer:

tsa of cylinder = 2πrh + 2πr^2

Step-by-step explanation:

=1760+1232

= 2992

is right answer

Answer 2

Answer:

First we have to use the formula which is 2paiR(height+radius)

Then we need to find the radius which is half of the diameter

Then use the formula and keep everything like 2 multiplied by 22 by 7 into 14 ( 20 + 14) then we can divide 7 and 14 where 14 gets replaced by 2 then it will come as 2 into 22 into 7 (20+14) then solve this we will get the answer as 2992cm
