C=πd
58π=πd
We conclude that
d=58 cm
r=1/2d
r=58(1/2)
r=29 cm
A=πr^2
A=29^2π
A=841π
Or
A≈2640.74 square cm. Hope it help!

Write the vertex form of the equation of the parabola which has a vertex of (0,0) and contains the point (1,2). A. Y=2x^2. B. Y=
Aleonysh [2.5K]
General equation of parabola:  y-k = a(x-h)^2

Here the vertex is at (0,0), so we have y-0 = a(x-0)^2, or y = ax^2

All we have to do now is to find the value of the coefficient a.

(1,2) is on the curve.  Therefore, 2 = a(1)^2, or 2 = a(1), or a = 2.

The equation of this parabola is y = 2x^2.
