Answer:
Step-by-step explanation:
total surface area= 616
4 \pi r^{2} =616 \\ \pi r^{2} =616/4=154 \\ r^{2} =\frac{154}{ \pi } \\ r^{2} =49 \\ r=7 cm
volume of the sphere= \frac{4}{3} \pi r^{3} \\ \\ \frac{4}{3} * \frac{22}{7} *49*7 \\ =1437.33

Answer:
4πr^2=616
r^2=616/4π=616×7/22×4
r^2=49
r=7 m
Vol. of sphere=(4/3)πr^3
=4×22×7×7×7/3×7
=4312/3 m^3
