Question

find the volume of metal in a hollow pipe of internal radius 3 cm ,metal 1 cm thick and the length6 cm whose answer is 132cm^3

Answer 1

Answer

Hope it's helps u you..

Step-by-step explanation:

Outer Radius = 3cm

Inner Radius = 1cm

Length = 6cm

Volume = πh (R2 - r2)

= 22/7 × 6 × (3^2 - 1^2)

= 22/7 × 6 × (9-1)

= 22/7 × 6 × 8

= 132cm^3

Answer 2

Answer:

r=1cm

R=3cm

h=6cm

vol=πh(R2-r2)

22/7×6×(3×3-1×1)

22/7×6(9-1)

22/7×6×8

22/7×48

132cm^3
