Answer:
169.65
hope this helps
have a good day :)
Step-by-step explanation:
Area=pi x r^2
so for the first area question, you would do a=pi x 5^2
a=78.539...
a=78.5cm^2 (It is shown on your screen as 25 pi but when simplified is this. Therefore, 25 pi is the correct answer.)
Use this for the rest of the area questions.
Answer:
Answer is 11
Step-by-step explanation:
At morning=0-1= -1
Afternoon=-1+15=14
Night = 14 -3=11
By definition, the speed is given by the quotient between the distance traveled and the time it takes to travel that distance. We have then that the expression for speed is as follows
v = d / t
where
d: distance
t: time
Substituting
v = (90feet) / (5s) = 18feets / s
answer
the average rate of the airplane model, in feet per second was 18feets / s
