Question:

A solid sphere has a diameter of 14cm.Find its surface area?

What to find:

The surface area

Information given in the question:

• A solid sphere has a diameter of 14cm

Solution:

Radius of the solid sphere=$\frac{14}{2}$cm=$7$cm

Note:$\pi =\frac{22}{7}$

The surface area=

$4*\frac{22}{7} *7*7$ $cm^2$

$= 616$ $cm^2$

Used formula:

The surface area of a solid sphere=$4*\pi* radius^2$

Answer:

The area of the solid sphere having diameter of 14cm=616$cm^2$
