Answer 1

since , we know that

original volume of cone = πr^2h / 3

since , the radius and height of cone increased by 10% then

Find the new radius:
----------------------------

new radius = r + 10% of r = r + 0.1r = 1.1r

Find the new height :
-----------------------------

new height = h + 10 % of h = 1.1h

Find the new volume:
------------------------------

new volume = π ( 1.1r )^2 ( 1.1h ) / 3

= 1.331 πr^2h / 3

Find the increase:
------------------------

increase = new volume - original volume

= (1.331 πr^2h/ 3 ) - ( πr^2h / 3 )

= πr^2h /3 ( 1.331 - 1 )

= 0.331 πr^2h/ 3

Find the increase% :
----------------------------

increase % =(increase × 100)/ original volume

= [ (0.331πr^2h /3 ) × 100 ] / (πr^2h / 3 )

= 0.331 × 100 = 33.1 %

Answer :
------------

volume of cone will be increased by 33.1 %
