GIVEN:

We are given a sphere with radius of 6cm.

Required;

To calculate the surface area of the sphere.

Step-by-step solution;

The surface area of a sphere is given by the formula;


Area=4\pi r^2

With the value of the radius given as 6, and the value of pi given as 3.14, we now have;


\begin{gathered} Area=4*3.14*6^2 \\ \\ Area=12.56*36 \\ \\ Area=452.16cm^2 \end{gathered}

Therefore,

ANSWER:

The surface area is


452.16cm^2
