Question

if the radius and height of a cone both are increased by 10% then the volume of cone is increased by how much

Answer 1

Step-by-step explanation:

Let height be 10cm

radius= 5cm

Vol of original cone = 1/3πr²h

= π/3 x 250

=250π/3

Height increased by 10% . Therefore new height = 11cm

Radius increased by 10%. Therefore new radius = 5.5cm

vol = 1/3πr²h

= 1/3πx332.75

=332.75π/3

Therefore vol increased = 332.75π/3/250π/3 *100

=332.75/250*100

=133.1%
