The answer to number 3
Reptile [31]

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.
