Question

10. In the diagram above, the cylinder has
diameter of 4 cm and height of 14 cm.
a) find the circumference of the base.
b) find the area of the base.
c) what is the volume of the cylinder?
[Take n = 22]
​

Answer 1

Given, height 14cm and diameter =4cm

Volume of a Cylinder of Radius "R" and height "h" =πR

2

h

Radius of the base =

2

4

=2cm

Hence, volume of the given cylinder =

7

22

×2×2×14=176cm

3

Answer 2

Answer:12.5cmc

Step-by-step explanation:circumference =

22 over 7 ×4cm

c=88cm over 7

c=12.
