​

Answer 1

Step-by-step explanation:

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

Answer 2

Answer:

The area of a circle is pi times the radius squared (A = π r²). Learn how to use this formula to find the area of a circle when given the diameter.

2 x radius - for diameter of circle

The perimeter or circumference of the circle can be found using the equation C=2π(r), where r= the radius of the circle.
