The figure shows an aerial view of a playground. If David runs around the field three times, he covers a distance of_____yards.
Andrew [12]

For this case, what we must do is find three times the perimeter of the figure.

The length of the arch is given by:

s = r * \alpha

Where,

r: radius of the circle

alpha: central angle in radians

We have then:

s = 35 * (\frac{280}{180}) * \pi\\s = 171 yards

Then, the perimeter of the figure is:

P = 3 * (171 + 45)\\P = 648 yards

Answer:

If David runs around the field three times, he covers a distance of 648 yards.

One number is 4 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 256 f
Lady bird [3.3K]

Answer: one number is 104, the first number is 26 and the third number is 126

How to:

Let’s say the “first number” is Y, the “second number” is X, and the “third number” is Z. This makes Y=4x and Z=x+100. Then put it into an equation to find the sum: X+4x+x+100=256. Take away 100 from both sides of the equation and combine the like terms (the X’s). That leaves 6x=156. Then divide both sides by 6 to get x alone which is x=26. That is the first number. To find Y just multiply X by 4 and that’s Y=104. And lastly add 100 to x which is Z=126.
