Given:
Radius of the base of the cone = 12 in.
The slant height of the cone = 15 in.
To find:
The lateral surface area of the given cone.
Solution:
The lateral surface area of the cone is:

Where, r is the radius of the base of the cone and h is the slant height of the cone.
Putting
, we get


The lateral surface area of the cone is 180π in ² and the missing value for the blank is 180.
2 * plane speed in still air = 289mph + 257mph = 546
plane speed in still air = 273 mph
plane speed in still air + wind speed = 289
273 + wind speed = 289
Therefore, wind speed = 16 mph
