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
