Question

the volume of a cylinder whose height is equal to its diameter is. Ans is 2pie radiuscube. please understand me I can't understand this question

Answer 1

so,
the height of the cylinder is equal to its diameter..
Imagine that the radious of the cylinder is r unit...so its diameter is 2r unit..
so, the height of the cone will be 2r unit(According to the question)
so the volume of the cylinder is
(π×r^2×2r)unit^3
=2πr^3 unit^3 (Answer)

hope you understand...if it helps pls mark me as brainliest..

Answer 2

let the diameter of the cylinder is D cm
then, the height of the cylinder is also Dcm
because diameter of the cylinder=height of the cylinder.
volume of cylinder=πr²h
π×d/2×d/2×d
22/7×d/2×d/2×d. ( π=22/7 and r=d/2)
11d³/14 Ans
But ur answer comes 2πr³ it is also right
because,
2×22/7×d/2×d/2×d/2=11d³/14.

both the answer is right.

I HOPE ITS CLEAR.
PLZZZ MARK IT AS BRAINLEIST..
