Answer:
22/7
Step-by-step explanation:
d=2
i.e r=d/2=1
then area of circle=πr^2
=22/7 *1
=22/7 i.e 3.1415
Answer:
16/3 or 5 1/3
Step-by-step explanation:
1. solve for X and y using both equations to find the point they cross in
−x − y = −5
y = x + 1
Plug in y into first equation
-x-(x+1)=-5
-x-x-1=-5
-2x-1=-5
+1 both sides
-2x=-4
÷-2 both sides
x=2 solve for y
y=2+1
y=3
(2,3)
2. you can set them equal to each other so 2x+4=3x+1
