Detailed Solution

Given that the radius of the sphere is 7cm.
The formula for the volume of sphere is given by,
Volume of a sphere

= 43 π r 3

, where r is the radius. So, after substituting the value of all the dimensions in the formula we get,

V = \frac{4}{3} \times (3.14) \times (7)^{3}

\Rightarrow V = \frac{4}{3} \times 3.14 \times 343

\Rightarrow V = 1436.03 c m^{3}

Therefore, the volume of sphere is

1436.03 c m^{3} .

Hence option (1) is correct.
