I need help with number 2 don’t understand it. someone help plz.

I would say solve each diameter equation and order them fromleast to greatest, for example

1 Venus- 7.52×10 to the power of 3
So first simplify 10 to the power of 3 which is, 1000. Then you multiply 7.52 by 1000 which gets you 7520.

So solve each equation and order it

What is the best approximation for the area of a circle with a diameter of 19 meters?

FromTheMoon [43]

$A = \pi r^{2}$ is the equation used for determining area from radius. We're given diameter, so to get the radius simply divide by 2. 19/2 = 9.5.

$A = (3.14)(9.5)^{2}$ , when solved, equals $283.385 m^(2)$ . After rounding to the nearest tenth, we get $283.4 m^{2}$
