The radius of some planet is 1106 miles. use the formula for the radius r of a sphere given its surface area A

The surface area of the planet as 15,371,637 square miles.

Step-by-step explanation:

Step 1:

We have the formula, where r is the radius of the planet and A is the surface area of the same planet.

By squaring both sides of the equation, we can substitute the value of r in the equation and determine the value of A.

So if we know the value of we can calculate the value of A.

If

Step 2:

By substituting the values, we get

Rounding this off, we get the surface area of the planet as 15,371,637 square miles.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
