We need to compute for the circumference of the circle and get 75% of the value because only 3/4 of the figure is a circle. 1/4 is substituted by the triangle.
I am assuming that the 35 yards is the radius of the circle.
Circumference = 3.14 * 2 * 35 yards = 219.80 yards
3/4 of the circumference = 219.80 * 3/4 = 164.85 yards
Perimeter = 164.85 yards + 45 yards = 209.85 yards
Ran round the field 3 times.
209.85 yards * 3 times = 629.55 yards
Anything Multiplied by 0 will be 0
The constant is 6. A constant is just the number on its own. Quadratics follow the form f(x) = ax^2+bx+c. The c is the constant.
So do you need it as a percent or a fraction?
