Given : a circle whose center is at (0, 0) and has diameter of 6cm
To Find : Which equation will satisfy
A. x²+ y² = 3
B. x²+ y² = 6
C. x²+ y² = 9
D. x²+ y² = 12
Solution:
Equation of circle center (h , k) and radius r is given by
( x - h)² + (y - k)² = r²
Center ( 0 , 0)
h = 0
k = 0
Diameter = 6 cm
radius = diameter/2
=> radius = 6/2 = 3 cm
r = 3
equation will satisfy the condition of a circle whose center is at (0, 0) and has diameter of 6cm
(x - 0)² + (y - 0)² = 3²
=> x² + y² = 9
x² + y² = 9 is the correct Equation
