Please solve question number 2 with process please its urgent ​

Answer 1

Answer:

Step-by-step explanation:

let the height be h

and radius be r

volume of cylinder=πr^2h

height is increased by 10%

new height=h+10%of h

h+10h/100

h+h/10

(10h+h)/10

11h/10

and radius is increased by 5%

new radius=r+5%of r

r+5r/100

r+r/20

(20r+r)/20

21r/20

new volume =π(21r/20)^2×11h/10

π×441r^2/400×11h/10

πr^2h(4851/4000)

change in volume=πr^2h(4851/4000)-πr^2h

πr^2h(4851/4000-1)

πr^2h(851/4000)

%increase in volume =change in volume×100/original volume

πr^2h(851/4000)×100/πr^2h

851×100/4000

85.1/4

21.275%

similarily we can find increase in tsa
