Answer:
Step-by-step explanation:
The area of a circle is :A= π r² r : the radius
A= 8π square units
so : π r² = 8π
r² = 8
r = √8 = √(4 × 2) =√4×√2
r = 2√2 units
Circumference=2πr
=2*3.14*105
=659.4cm
Answer:
y = square root x2 - 5
Step-by-step explanation:
Since, the system of linear equations are parallel
so, they will never cross or intersect each other
And we know that
solution can only be found if both lines intersect atleast one point
But here , lines are parallel
so, they never intersect each other throughout number line
Since, they never intersect
so, we won't get any common value between both lines
Hence,
There is no solution...........Answer
