Answer:
c = 4
Step-by-step explanation:
Step 1: First, you have to regroup terms.
3 = 4c − 13
Step 2: Then, Add 13 to both sides.
3 + 13 = 4c
Step 3: Next, you simplify 3 + 13 to 16.
16 = 4c
Step 4: Then divide both sides by 4.
Step 5: Simplify into to 4.
4 = c
Step 6: Lastly, switch sides and you're done!
c = 4
Answer:
Step-by-step explanation:
Circle is centred at (0, -2)
-> h = 0 & k = - 2
radius of the circle (r) = y-coordinate of the center = - 2
Equation of circle in standard form is given as:
Plugging the values of h, k and r in the above equation, we find:
This is the required equation of circle.
