Answer: 1.1 × 10⁸ cm³


Step-by-step 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
