Answer:
r=12.5 units
Step-by-step explanation:
Well assuming that DM means diameter of a circle, then r should be the radius of the circle.
Diameter of a circle is twice the radius of the circle, hence with the value of Diameter, you should half it to get the value of radius.
Given diameter =25
Radius will be= 25/2 = 12.5 units
Answer:
Step-by-step explanation:
radius=4 as it is tangent to x-axis.
y co-ordinate of center is 4 so radius=4
eq. of circle is (x-2)²+(y-4)²=4²
or x²-4x+4+y²-8y+16=16
or x²+y²-4x-8y+4=0
(x, y)
The domain are all the x-values, the range are all the y-values.
R={(19,96),(20,101),(21,106),(22,111)}
The domain is: 19, 20, 21, and 22
The range is: 96, 101, 106, and 111
