Answer:
28.26 square inches
Step-by-step explanation:
Formula for area of a circle:

Radius is 3.

Use 3.14 for pi:

The area should be 28.26 square inches.
Answer:
6 units
Step-by-step explanation:
The formula for a trapezoid is ((b1+b2)/2)h.
Here, we see b1 = 8 and b2 = 17.
If the area of the trapezoid is 75, we can make the equation :
75 = ((8+17)/2)x , where we would solve for x.
First, we simplify the right side of the equation :
75 = (25/2)x
Multiply both sides by 2 to get rid of the "/2"
150 = 25x
Then divide both sides by 25.
6=x
We are given:
The time t required to drive a certain distance varies inversely with the speed r.
According to the question t is inversely proportional to speed(r).
let us say distance (d) is constant of proportionality,
So the equation becomes,

Now from the question, we are given it takes 2 hours to drive the distance at 67 miles per hour, so plugging these in the above equation,

d=134 miles.
Now we have to find how long will it take to drive the same distance that is 134 miles at 55 miles per hour
so plugging the values, we have,

t=2.436
So the time taken will be around 2.5 hours.
Answer : It will take about 2.5 hours to drive the same distance at 55 miles per hour. Option C. About 2.5 hours.
