The circumference of the trunk of a tree cylindrical in shape is 132 cm find the volume of timber that can be obtained from a trunk if the length of the trunk is 1.5 meter.
║⊕ANSWER⊕║
Circumference = 132 cm .
2π r = 132
⇒ r= 66/π
⇒r = 21 cm
Length of trunk h = 1.5 m
= 1.5 ×100
= 150 cm
Volume of timber = π r² h
= (22/7) ×(21)²×150
=207900 cm³
