Answer 2

Answer:

Volume of the sphere  =  5.42 cm cube

Step-by-step explanation:

Surface Area of a Sphere = 4π$R^{2}$            (take π = 22/7)

So, 4π$R^{2}$ = 15

or, $4 \times \frac{22}{7}  \times R^{2}  = 15$

from here, $R^{2}  = 1.19 cm$

So, R = 1.09 cm

Now, Volume of the sphere is $\frac{4}{3} \pi R^{3}$

putting R = 1.09 and π = 22/7,

we get Volume of the sphere  =  5.42 cm cube
