Answer:
Ms. Thomas was driving at constant rate of 52 miles/hour.
Step-by-step explanation:
Given:
Total time to travel (t) = 45 minutes
Distance drove (d) = 39 miles
we need to find the constant rate in miles per hour at which she was driving.
Solution:
Now we know that;
We need to find constant rate at miles per hour;
But time is given in minutes.
So we will convert minutes into hour by dividing by 60 we get;
time 
Now we know that;
Distance is equal to rate times time.
framing in equation form we get;
distance 
Or
rate 
Hence Ms. Thomas was driving at constant rate of 52 miles/hour.

Answer:
87.92 cubic inches
Step-by-step explanation:
to find the volume of a cylinder the formula is V = 
h
so first i squared 2
2x2= 4
i then multiplied 4 by the height (7)
4x7 = 28
then times 28 by pi (3.14)
28x 3.14 = 87.92
