Answer: the radius is 1/2 times the diameter
Step-by-step explanation:
sorry if wrong
The equation of a circle with centre (a,b) and radius r is:
(x - a)^2 + (y - b)^2 = r^2
thus,
here centre (a,b) = (-3,6), a = -3, b = 6
and radius = diameter/2 = 20/2 =10 units
therefore, the equation is
(x + 3)^2 + (y - 6)^2 = 100
which is c.
Step-by-step explanation:
fro the figure
2z = 68
z = 68/2
z =34
also
v + 68 = 180
v = 180 - 68
v = 112
also
v = x
