Remark

It is really hard to tell what the playground is. Is he running around 45 yards plus the circumference of part of the circle? Or is just the triangle? Since pi is mentioned, I'll take it to be 45 + part of the circumference, but the ambiguity makes it possible to be wrong.

Equation

Distance = 2* (280/360) * pi * r + 45

Givens

r = 35 yards

Solve

C = 2 * 3.14 * (280/360) * 35 + 45

C = 2 * 3.14 * (0.77777777) * 35 + 45

C = 6.28 * 35 * 0.777777 + 45

C = 170.9555556

Answer

C = the distance for 1 lap around the playground. David went around 3 times.

3*C = 3 * 170.95555556

3C = 512.8666667

The distance he went is 513 yards <<<< Answer

Describe and correct the error a student made in finding the midpoint cd with c(-4,5) and d(-1,-4).
Gnesinka [82]

Answer:

Step-by-step explanation:

The formula for finding the midpoint of two coordinates is expressed as;

M(X,Y) = (\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})

Given the coordinates c(-4,5) and d(-1,-4), x1 = -4, y1 = 5, x2 = -1 and y2 = -4.

For the X coordinate of the midpoint

X = x1+x2/2

X = -4+(-1)/2

X = -4-1/2

X = -5/2

X = -2.5

Similarly for Y:

Y = y1+y2/2

Y = 5+(-4)/2

Y = 5-4/2

Y = 1/2

Y = 0.5

Hence the midpoint coordinate of C(-4,5) and D (-1,-4) is (-2.5, 0.5)
