Answer:
<h2>22 meters.</h2>
Step-by-step explanation:
It's important to notice that the area is circular, which is defined by

Replacing given values and solving for r, we have

But, the diameter is twice the radius, so

Therefore, the diameter is 22 meters.
Answer:
7
Step-by-step explanation:
y = 60x + 150
550 - 150 = 400
400/60 = 6.66666...
Round up as you can't sell just part of the car.
He must sell 7 cars
Well, if you use the net diagram, the one below the pyramid, this is how to do it:
First, find the area of the square, or the base. That would be 10 * 10 = 100ft.
Then, you find the areas of all of the triangles, which is this formula: A= BH / 2.
So you would do 10 * 12 / 2 for each triangle, or you can just make them squares, since there are four triangles, and it would turn into 10 * 12 * 2 for all of them. That was just an easier way to figure it out, but you could have done each triangle and then added them all up.
Finally, add what you get for the triangles, 240ft, with the area of the square, 100ft. You get 340ft².
Your answer will be 340ft².

Distance at which the lake is located = 60 miles
Speed at which Rene traveled the entire distance = 40 miles per hour
We already know that
Speed = Distance/Time
Then
Time = Distance/speed
= 60/40 hours
= 3/2 hours
= (3/2) * 60 minutes
= (3 * 30) minutes
= 90 minutes
Rene will take 90 minutes to reach the lake.
