The given sphere has a diameter d=7 cm.

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

$SA=4\pi r^2$

Where r is the radius, it is half the diameter. So r=3.5 cm.

By replacing this value, we can find the surface area:

$\begin{gathered} SA=4\pi(3.5cm)^2 \\ SA=4\pi *12.25cm^2 \\ SA=49\pi\text{ }cm^2 \end{gathered}$

The surface area of the sphere is 49pi square centimeters.
