Suppose a spherical asteroid has a radius of approximately 9.0 x 10^2m. Use the formula 4/3*pi
r^3 to find the approximate volume of the asteroid.

2.57 * 10^9 m^3
1.07 * 10^4 m^3
2.54 * 10^10 m^3
4.51 * 10^10 m^3

I've worked 4/3*pi*10^2 = 900 meters... but now I'm confused, but I know it's something to do with 900^3... please help?

1. (9*10*2)^3 = 9^3 *10^6
so
(4/3) pi 9^3 * 10^6

4 * 81*9 * 10^6
