The volume of the blue ball is about 1.5 times larger than the volume of the red ball.
To calculate the volume of a sphere, you use the formula V = (4/3) * π * r^3. Since the diameter is given, we need to divide it by 2 to get the radius.
For the blue ball:
r = 56 cm / 2 = 28 cm
V_blue = (4/3) * π * 28^3 ≈ 14366.24 cm^3
For the red ball:
r = 76 cm / 2 = 38 cm
V_red = (4/3) * π * 38^3 ≈ 29326.65 cm^3
So, the volume of the blue ball is about 1.5 times larger than the volume of the red ball.
