Question

if radius of the hemisphere is increased by 100% then what percentage will increase in the volume ​

Answer 1

Answer:

200%

Step-by-step explanation:

Let the initial radius be R

New R or R' = 2R because radius is increased by 100%

Initial Volume = 4/3 π R^3

New Volume = 4/3 π (2R)^3

or 4/3 π 8R^3

Increase in Volume = 4/3π [8R^3-2R^3]

or 4/3π 6R^3

Increase Percent = Increase in Volume / Initial Volume × 100 %

=4/3 π 6R^3/ 4/3πR^3 × 100 %

= 200 %
