A mini basketball is spherical in shape
There volume, "V'<span> of a sphere is given by
V = (4/3) </span>π·r^3
Where r is the radius of the sphere
Given
Volume, V = 230 cubic inches
π = <span>22/7
</span>
V = (4/3) π·r^3
230 = (4/3) * (22/7) * r^3
230 = 4.19 * r^3
230/4.19 = r^3
54.89 = r^3
Since, r^3 = 54.89
r = ∛(54.89)
r = 3.8 inches (<span>to the nearest tenth</span>)
