Answer:
Elena won the race.
Step-by-step explanation:
If you calculate it, Lin runs a mile every 9 minutes.
9 times 7.5= 67.5 which is 1 hour, 7 minutes and 30 seconds. While it took only an hour for Elena to run 7.5 miles.
Which means Elena's speed was faster and got her to the finish line first.

Total surface area of cone is 176π
<h3>Explanation:</h3>
Surface area of curved surface of a cone is give by π⋅r.l , where r is the radius and l is the slant height of the cone.
Hence surface area of curved surface of a cone is π×8×14=112π .
As surface area of base is π×82=64π .
Hence total surface area is 112π+64π=176π
