Question

A cylinder is 21 cm in height and its volume I s1056 sqcm. Find the diameter of its base.​

Answer 1

176 is the answer for this question

Answer 2

8 cm

Step-by-step explanation:

We use formula for volume of cylinder I. e. πr^2h

and by putting the value of π , h and putting 1056 is in equal so we get 22/7 X 21 X r^2 = 1056

we get r^2 = 16 ( by solving )

and when we find the √16 = 4 cm .

raidus is 4 cm .

so diameter is 4 X 2 = 8 cm .

I hape you understand .
