A circle is described by the equation (x−1/2)squared+(y−3/2)squared=4/9. What are the coordinates for the center of the circle a
nd the length of the radius? (-1/2,-3/2), 2/3 units (-1/2,-3/2), 4/9 units (1/2,3/2), 4/9 units (1/2,3/2), 2/3 units
1 answer:
(x-1/2)² + (y-3/2)² = 4/9
For any circle in the standard form (x-h)² + (y-k)² = r², the center is at (h, k) and the radius is r.
In the case of our equation here. the center is at (1/2, 3/2) with a radius of 2/3.

Step-by-step explanation:
Answer:
x^2 = 10^2 - 9^2
x^2 = 100 -81 = 19
x = 4.3588989435
The triangle sides are 10, 9 and 4.3588989435
