<h3>What is the equation of a circle?</h3>
The equation of a circle of center
and radius r is given by:

From the graph, it can be seen that the center of the circle is (0,0), thus
and the radius is of r = 10, hence the equation is:

Answer:
A
Step-by-step explanation:
because it goes up constantly by 12
Step-by-step explanation:
we can find the value of c by Pythagoras theorem
according to Pythagoras theorem
h² = a² + b²
where
h = hypotenuse (i.e. longest side of a right angled triangle)
a = side
b = base
so, we have to find h or hypotenuse here
h² = (24)² + (18)²
h = 576 + 324 = 900
h² = √900 = 30
c = 30
therefore, value of c is 30.
Hope this answer helps you dear!
