Question

find the height of cylinder whose radius is 7 and total surface are in 1100 CM square

Answer 1

HEY Buddy.....!! here is ur answer

Given that... the radius of the cylinder = 7cm.

and Total surface area = 1100 cm.

Let, the height of cylinder = h cm.

As we know that = 2πrh + 2πr² = 2πr(r+h)

Now, according to the question....

2πr(r+h) = 1100

=> 2×22/7×7(7+h) = 1100

=> 44(7+h) = 1100

=> 7+h = 1100/44

=> 7+h = 25

=> h = 18 cm

Thus, the height of the cylinder = 18 cm

I hope it will be helpful for you....!!

THANK YOU ✌️✌️

Answer 2

Total surface area=1100cmsquare
Radius=7cm.
Now,

$h + r$
