Suppose a company did $3,000,000 in annual maintenance in 2013 and expects 85% of those to renew for 2014. Suppose that product
sales for 2013 were $3,000,000 (which included free maintenance in 2013) and 60% of those were expected to pay an annual maintenance of 20% of the purchase price in 2014. What will be the annual maintenance collected in 2014?
The radius of your cone is half of 18 units = 9 units.
The volume of any cone is <span><span>V = (1/3) · (pi) · (radius)² · (height) </span> </span> -- Take that formula for the volume of any cone. -- Write '8' in place of 'height'. -- Write '9' in place of 'radius'. -- Write '3.142' in place of 'pi'. -- Complete the arithmetic. -- Bada-bing, you've got the volume.
