Question

A log of wood in the shape of the cylinder has length 2m and diameter 70cm find the volume of wood in the log. (pie=22/7)​

Answer 1

Answer:

Step-by-step explanation:

step-by-step explanation:

L=2m  

R=0.35m

Volume = pi×r×r×h  

2 X 0.35 X 0.35 X 22/7

2.2 X 0.35  

0.77

Answer 2

The Volume of cylinder = πr²h

d = 70 cm

so radius is 70/2 = 35cm

height (length) = 2m

convert metre into cm,

so the height is 200cm

now we have all the values

π = 22/7

r = 35 cm

h = 200 cm

Substitute the values you will get

πr²h

$\frac{22}{7}$ x 35 x 35 x 200

22 x 5 x 35 x 200

4400 x 175

770000 cm³
