Mathematical problem: Cut a cylindrical wood with a base circumference of 18.84cm and a height of 10cm into the largest cone. What is the cutting volume? The volume of the cone is
Radius 18.84 ÷ 3. 14 ÷ 2 = 3cm.
Cut off the volume is:
3. 14×3×3× 10×( 1- 1/3)
=3. 14×60
=188.4cm3
The volume of the cone is:
3. 14×3×3× 10× 1/3
=94.2 cubic centimeters
