To calculate the diameter of a circle, multiply the radius by 2. If you don't have the radius, divide the circumference of the circle by π to get the diameter. If you don't have the radius or the circumference, divide the area of the circle by π and then find that number's square root to get the radius. To find the area of a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.Write down the formula for finding the circumference of a circle using the diameter. The formula is simply this: C = πd. In this equation, "C" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi.

The plane flew a total of 2,220 miles at an average speed of 555 miles per hour. The duration of the flight can be determined by using the formula for time (t = d/v). In our case, the flight took 4 hours.
To calculate the duration of the flight, we can use the following formula for time (t), which is:
t = d/v, where d is the total distance traveled and v is the average speed.
Given our values: d = 2,220 miles and v = 555 miles per hour, plug these into our formula and solve for t (time in hours). So, our calculation becomes: t = 2,220 miles / 555 miles per hour.
The result of this calculation is t = 4hours. Therefore, it took the plane 4 hours to fly a total distance of 2,220 miles at an average speed of 555 miles per hour.
