Question

Find the surface area to the nearest tenth.19 m4536.5 m22268.2 m2O 238.8 m2477.5 m2

Answer 1

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.
