Volume of the beach ball: 4/3*pi*radius^3
10 inches
You'll need to know its radius because its volume = 4/3*pi*radius cubed
First we have to find the radius because the diameter is twice the radius: 4/3*pi*radius3 = 28 radius = 1.883749459 (worked out by making the radius the subject of the formula) diameter = 3.767498918 or 3.77 inches to 2 d.p.
Volume formula for a sphere is 4/3*π*r3 so volume of ball with radius of 4.6 cm is 4/3*3.14159*(4.6cm)3 = 407.72 cm3
