Area of circle = πr²
Find radius:
πr² = 1808.64
r² = 1808.64 ÷ π
r² = 575.71
r = √575.71
r = 23.99 units
Find Circumference:
Circumference = 2πr
Circumference = 2π (23.99)
Circumference = 150.76 units
Answer: Circumference = 150.76 units
Answer:
True
Step-by-step explanation:
Here, we want to check if the given equation does not intersect the x-axis
if it does not, then it has no real root
If the discriminant is less than zero, then it has no real roots and does not intersect the x-axis
The formula for the discriminant is;
D = b^2-4ac
In the question;
a = -1 , b = 6 , c = 10
so;
D = 6^2-4(-1)(10)
D = 36-40
D = -4
Since discriminant is less than zero, then there is no real root and the graph does not cross the x-axis
Answer:
104 degrees
Step-by-step explanation:
90 + 54 + 132 = 276
360 - 276 = 104
It should be B
Because the slope of AB is 6/5 and when you are finding it’s perpendicular bisector then the slope of that line should be the negative reciprocal, it should be -5/6.
