Answer 2

Answer:

Step-by-step explanation:

Surface area of sphere is = $4\pi r^2$

$196\pi \: =\:4\pi r^2\\\frac{196\pi }{4\pi }=r^2\\49=r^2\\\sqrt{49} = r\\7 = r$

Now, Volume of sphere

 $=\frac{4}{3} \pi r^3\\=\frac{4}{3}*\frac{22}{7} *7*49\\=\frac{4*22*49}{3} \\=\frac{4312}{3} \\= 1437 cm^3$
