Question 2:

See the 2nd attachment (figure)

SolutioN:

Inner radius =

24/2

=12cm

Outer radius =

28/2

=14cm

Height = Length of pipe =35cm

Volume = π(r2- r2)h

Volume = 22/7 × (14 square -12 square)× 35

Volume = 5720cm

Mass of pipe =(5720×0.6)g=3432g=3.432kg

Question:3

(i). Given:

• Length=5cm,
• Width=4cm,
• Height =15cm

V=l×b×h

=5×4×15=300cm

(ii). Given:

• Diameter =7cm,
• Height=10cm,

$r\: = \frac{7}{2}$

$Volume =\pi {r}^{2} h$

$= \frac{22}{7} \times \frac{7}{2} \times \frac{7}{2}$

=77×5=385cm

Difference =385cm −300cm

=85cm

.

Hence, Cylinder container has greater capacity by 85 cubic cm.
