Question

a log of wood in the shape of a cylinder has length 2m and diameter 70cm find the volume of wood in the log($\pi =22/7$)

Answer 1

Step-by-step explanation:

length h = 2m

diameter = 70cm = 70/100 = 0.7m

2r = 0.7m => r = 0.35 m

volume of wood in the log

= πr^2h

= 22/7)*(0.35)^2*(2)

= 0.77m^3 or 770000cm^3

Ans.

Answer 2

Step-by-step explanation:

Volume = πr^2(h)

= (22/7)(35*35)200

= 22000*35 =770000 cm^3
