An equation of the circle is
(x-h)² +(y-k)² =r²,
where (h,k) are coordinates of the center of the circle, and r is a radius of the circle.
We have h=2, k= -1, and radius r=diameter/2=10/2=5.

The equation of our circle is 
(x-2)²+(y+1)²=25

The center of a circle is at the origin on a coordinate grid. A line with a positive slope intersects the circle at (0, 7). Whic

The true statement is the circle has the radius equal to 7.

<h3>What is Equation of circle?</h3>

The general equation for a circle is (x-h)² + (y-k)² = r², where ( h, k ) is the center and r is the radius.

As, standard form of equation of circle is

(x-h)² + (y-k)² = r²

At origin, equation of circle will be

(0-h)² + (0-k)² = r²

r² = x² + y²

Now, The line intersects the circle at (0,7)

r² = 0² + 7²

r² =49

r=7.

Hence, the circle has the radius equal to 7.
