Question

the radius of a sphere is increased by 10%.percentage increase in volume

Answer 1

let radius be r
volume =4/3(22/7×r^3)
radius =r+10%of r=r+(r/10)=11r/10
now new volume =4/3(22/7×1.1r×1.1r×1.1r)
now increase in volume =new volume -volume
percent increase in volume =(increase in volume×100)/original volume

Answer 2

Answer:

Step-by-step explanation:

Let radius be r

Volume =4/3(22/7xr^3)

Radius =r+10%of r =r+(r/10)=11r/10

Now volume is =4/3(22/7x1.1rx1.1rx1.1r)

Now increase are in volume =new volume -volume

Percent increase in volume =(increase in volume x100)/original volume
