Answer:
363
Step-by-step explanation:
Formula for area of a circle
A = πr^2
Where r = radius
The circle has a given radius of 11
To find the area of the circle we simply substitute r in the formula with the value of the radius (11)
( Also note that the question says to use 3 for π )
A = πr^2
π = 3
r = 11
Substitute values in formula
A = (3)(11)^2
11^2 = 121
A = 121(3)
121(3) = 363
A = 363

Answer: 0.57
Step-by-step explanation:
Given : The speed of cars on a stretch of road is normally distributed .
Population Mean = 
Standard deviation : 
Let x be the random variable that represents the speed of cars on a stretch of road .
z-score : 
For x= 50.
By using the standard normal distribution table ,
The probability that a randomly selected car is violating the speed limit of 50 miles per hour :-
