The formula for the lateral area of a cone
is:

Where:
is the radius of the circular base of the cone
As we know its diameter
, its radius is 
is the height of the cone

I believe, the answer is 117.5
To find the percent increase, you will first find the difference in price for the peak season economy and the regular economy price.
$526.3-$440.8=$85.50

85.50/440.8= 0.19
The percent increase is approximately 19%.
Answer:

Step-by-step explanation:
<u><em>Given that:</em></u>
R is a point lying on line TS
So,
TS = TR + RS
Where TR = 4.5 and RS = 6
=> TS = 4.5 + 6
=> TS = 10.5
