In this question , it is given that we have a cylinder with with a radius of 9 and a surface area of approximately 791.68 units square.
The formula of surface area of cylinder is
Substituting the values of A and r, we will get
So the height of the cylinder is 5 units .
Answer:
Actual distance between the two cities given on the map = 78.0 miles
Step-by-step explanation:
Scale used for the actual distance between two cities on a map is,
5 in. = 15 mi.
in. =
mi.
1 mi. = in.
1 inch = 3 miles
Therefore, 26 inches on the map = 26 × 3
= 78 miles
Therefore, actual distance between the two cities given on the map = 78.0 miles
