I would say herself, she’s not good at taking criticism and makes her own schedule, sounds like she would have trouble in another environment
Surface area of cone can be calculated using the following rule:
area of cone = pi (radius)^2 + pi (radius) (height)
we have the area and the radius as given and the value of pi is a constant = 22/7.
So, all we need to do is just substitute in the above equation to get the value of the height as follows:
500 pi = pi (15)^2 + pi (15)(l)
we will divide all terms by pi
500 = (15)^2 + 15l
15l = 500 - (15)^2
15l = 275
l = 275/15 = 18.334 ft
900,000 should be correct. :)
