Question

anonymous · Answer

A cone-shaped piece of baker’s chocolate has a radius of 3 cm and a height of 9 cm. Samia shaves off some of the chocolate. The remaining piece is still shaped like a cone with a radius of 3 cm, but the height is 6 cm.
 
How much chocolate did Samia shave off?
Use 3.14 to approximate pi and express your final answer in hundredths.
 
_____  cm^3

igreen · Answer

Find the volume of the two cones and subtract.

igreen · Answer

$V = \dfrac{1}{3} \pi r^2 h$

Plug in 3 for the radius and 9 for the height and 3.14 for pi.

anonymous · Answer

1/3 x 3.14 x 3^2 x 9 = 84.78

igreen · Answer

Yep, now for the other one:

$V = \dfrac{1}{3} \pi r^2 h$

Radius = 3
Height = 6

anonymous · Answer

56.52

igreen · Answer

Yep, now subtract 84.78 - 56.52

anonymous · Answer
