Answer:
The circumference of the circle is .
Step-by-step explanation:
A sector is the part of a circle enclosed by two radii of a circle and their intercepted arc. A pie-shaped part of a circle.
The area of a circle is given by
The formula used to calculate the area of a sector of a circle is:
The circumference of a circle is the distance around the outside of the circle and its given by
We know the central angle = 110º and the area of the sector 50 units squared.
First, we use the formula to calculate the area of a sector to find the radius.
The radius can't be negative. Therefore,
Next, we apply the formula for the circumference of a circle.
Answer:
Third zero is -1.
Step-by-step explanation:
consider the given polynomial is
It is given that -1 and -3 are two zeroes, therefore (x+1) and (x+3) are two factors of given polynomial.
The given polynomial can be rewritten as
Now, splitting the middle term, we get
Here, power of (x+1) is 2. It means the multiplicity of zero -1 is 2.
So, three zeroes are -1, -1 and -3.
Therefore the third zero is -1.
