In terms of its radius , the volume of the balloon is
The diameter is twice the radius, so that in terms of its diameters, the balloon's volume is given by
Differentiate both sides with respect to time :
The diameter increases at a rate of . When the diameter is , we have
or about 23,562 cc/min (where cc = cubic centimeters)
sqrt(81) = 9
sqrt(100) = 100
sqrt(92) is between 9 and 10.
