Question

If the radias and height of a cone both are incoreased
by 10% how much increase will be there in its volume​

Answer 1

Answer:

33.1%

Step-by-step explanation:

volume of cone, V = Pi ×r^2×h/3

height increased by 10% = h×(1+10%) =1.1h

radius increases by 10% = r×(1+10%) =1.1r

new volume, V1 =pi×(1.1r)^2×1.1h/3

=1.331×pi×r^2×h/3

=1.331×V

%increase in Volume = V1 -V / V

=1.331V -V/V

=.331×100 =33.1%
