Answer:
The height of right circular cone is h = 15.416 cm
Step-by-step explanation:
The formula used to calculate lateral surface area of right circular cone is: 
where r is radius and h is height.
We are given:
Lateral surface area s = 236.64 cm²
Radius r = 4.75 cm
We need to find height of right circular cone.
Putting values in the formula and finding height:

So, the height of right circular cone is h = 15.416 cm

We need to find thr rate of change (slope) of the line joining these two points ~





Slope of the line (m) joining the two points is 2 ~
If the two quadrilateral are congruent, then ABCD = PQRS is the correct congruence statement.
