Answer 2

The volume of the sphere is 4.851 cm cube then the surface area is 13.85 square centimeter

Solution:

Given that the volume of sphere is 4.851 cm cube

We have to find the surface area

The formula for volume of sphere is given as:

$v = \frac{4}{3}\pi r^3$

Where "r" is the radius

Substituting the value of volume we get:

$4.851 = \frac{4}{3}\pi r^3\\\\3 \times 4.851 = \frac{22}{7}r^3\\\\r = 1.05$

The surface area of sphere is given as:

$Surface area = 4 \times \pi \times r^{2}$

Substituting "r" value we get:

$surface area = 4 \times 3.14 \times (1.05)^2 \\\\= 13.85$

Hence surface area of sphere is 13.85 cm square
