Question

A laser pointer in the shape of a cylinder is 13 centimeters long with a radius of 1 centimeter. On top, it has a cone-shaped tip with a height of 3 centimeters. What is the volume of the laser pointer in terms of π?

Answer 1

Answer:13*pi+pi-----> 14*pi cm³

Step-by-step explanation:

We know that

volume of a cylinder=pi*r²*h

where

h=13 cm

r=1 cm

volume of a cylinder=pi*1²*13----> 13*pi cm³

volume of a cone=(1/3)*pi*r²*h

where

r=1 cm

h=3 cm

volume of a cone=(1/3)*pi*1²*3-----> pi cm³

volume of the laser pointer=13*pi+pi-----> 14*pi cm³

Hope this helps:)
