Answer:

Step-by-step explanation:

The given solid is a sphere of radius 19m.

The surface area of a sphere is calculated using the formula:


A=4\pi r^2

Substitute 19 for r:


\begin{gathered} A=4*\pi*19^2 \\ =4536.46m^2 \\ \approx4536.5\; m^2 \end{gathered}

The surface area of the sphere to the nearest tenth is 4536.5 square mete.
