Answer:
A≈50.27
Step-by-step explanation:
The formula for an Area of a circle is: A=πr(squared)
As was can the the diametter is 4, and the radius is half of the diameter, making the radius half of 4 whitch is 2. now just plug in two for R.
A= π4(squared)
4(squared) = 16
A= 16π
A= 50.27
Step-by-step explanation:
x+y=-12
x-y=-2
solve by simultaneous equations multiply the second equation by -1
-x-y=2
subtract both equations
y=10
x+10=-12
×=-22
Since the scale factor of the dilation is 2, you would multiply each of the pre-image line segments' lengths by 2.
therefore,
P'Q'=4cm
A'B'=3cm
M'N'=6cm
Hope this helps you out!
What? y=x and y=x-3 are parallel lines there is no solution
