Sara goes on a slingshot ride in an amusement park. She is trapped into a spherical ball that has a radius of 3•100 centimeters. What is the volume of air in the spherical ball.

Answer: 1.1 * 10⁸ cm³

Explanation:

1) Since the ball is spherical, you use the volume formula for a sphere, which is:

Volume = [4/3] π r³

2) r is the radius, which is given and is equal to 3*100cm = 300cm

3) Pluging in the value of r, you get:

Volume = [4/3] π (300 cm) ³ = 113,097,335.53 cm³

4) Since, r = 3*100 cm has two significant figures, the result must show only two significant figures.

So, using scientific notation, the right answer must be reported as: 1.1 * 10⁸ cm³
