The volume (in cm³) of a wire of diameter 14 cm and length 30 m is: $$Take \pi = \frac{22}{7}$$​​

Correct option is C

Given:

Diameter of the wire = 14 cm

Radius r =$$\frac{14}{2}$$​= 7 cm

Length of wire h = 30 meters = 3000 cm

π $$= \frac{22}{7}$$​​

Formula Used:

Volume of Cylinder $$= \pi r^2 h$$​

Solution:

Volume=$$\frac{22}{7} \times (7)^2 \times 3000$$​

​$$= \frac{22}{7} \times 49 \times 3000$$​

=$$22 \times 7\times 3000$$​​

= 462000$$\, \text{cm}^3$$​
