The x intercept ? I think this is what you mean
Answer:
194.78 yards
Step-by-step explanation:
Diameter: d=62yards
Perimeter: p=2×pi×r=pi×d, where d=2×r, r being the radius.
We get: p=pi×d=62×pi=194.78 yards
≈9.38
13² - 9² = x²
189 - 81 = 88
√88 = x
1/2y^2=1/2x^2+8. The curve's slope at (x,y) is x/y, so dy/dx=x/y. To solve this differential equation, rearrange it to: y*dy=x*dx, and by integrating both sides, we get 1/2y^2=1/2x^2+C (some constant). Plug in (0,4) into this equation, 8=0+C, so C=8. The curve's equation is 1/2y^2=1/2x^2+8.
