Question

A cylindrical type of wooden pencil is sharpened to produce a cone at one end with no less of length .if the diameter of the pencil is 1cm and length of conical portion is 2cm. Find the volume of the wood got due to sharing

Answer 1

Answer:

$\frac{11}{21}$

Step-by-step explanation:

Diameter = 1 cm

Radius = 0.5 cm

Height of cone = 2 cm

Solution = Volume(cylinder) - Volume(cone)

= $\pi$r²h - $\frac{1}{3}$$\pi$r²

= $\frac{2}{3}$$\pi$r²

= $\frac{2}{3}$×$\frac{22}{7}$×0.5²

= $\frac{11}{21}$
