If you mean: x²+y²+14x-10y = 250 then:
A circle with centre (x0, y0) and radius r has formula (x - x0)² + (y - y0)² = r²
x² + y² + 14x - 10y = 250
→ x² + (2×7)x + y² + (2×5)y = 250
→ x² + (2×7)x + 7² - 7² + y² - (2×5)y + 5² - 5² = 250
→ (x + 7)² - 49 + (y - 5)² - 25 = 250
→ (x + 7)² + (y - 5)² = 324
→ (x - -7)² + (y - 5)² = 18²
→ The radius of the circle is 18 and its centre is at (-7, 5).
Radius = 1111
Type your answer here. Find the radius for a circle with the equation x2 plus y2 equals 9? ..
Equation of a circle centre the origin is: x2 + y2 = radius2 ⇒ radius = √9 = 3.
x^2+y^2=36
A circle centre (0, 0) and radius r has equation x² + y² = r² The circle x² + y² = 36 has: r² = 36 → radius = 6

If that equals 16 then the radius is 4
x^2+y^2=36
A circle centre (0, 0) and radius r has equation x² + y² = r² The circle x² + y² = 36 has: r² = 36 → radius = 6
9
7
8
That's the equation of a circle with its center at the origin and a radius of 8.
The radius is sqrt(12) = 3.464 (rounded)
The ' 1 ' in that equation is the radius.
