Answer:

4.5×10^17 m²

Step-by-step explanation:

The radius is half the diameter, so we can make the substitution r=d/2 into the formula to get ...

A = 4πr² = 4π(d/2)² = πd²

Filling in the given values and doing the arithmetic gives ...

A = 3.14×(3.8×10^8 m)² = 45.3416×10^16 m²

A ≈ 4.5×10^17 m²

We round to 2 significant digits because that is the precision of the given diameter.
