b. 452.16 sq. in.
c. 18.84 sq. in.
d. 113.04 sq. in.
we know that
Area of the circle is equal to
where
r is the radius
in this problem
therefore
the answer is the option
d. 113.04 sq. in.
The area of the Frisbee is about 113 in.² ( Option D )
The basic formula that need to be recalled is:
Circular Area = π x R²
Circle Circumference = 2 x π x R
where:
R = radius of circle
The area of sector:
The length of arc:
Let us now tackle the problem!
Given:
Diameter of Frisbee = d = 12 in
Unknown:
Area of Frisbee = A = ?
Solution:
Area of the Frisbee could be calculated using the area of circle as follows:
The closest option available will be option D. 113 in.²

Answer:
The line of symmetry is x=2
Step-by-step explanation:
Given:
We are given a quadratic equation and to find the line of symmetry.
As we know the line of symmetry of parabola passes through the x value of vertex.
If vertex of parabola is (h,k) then equation of line of symmetry x=h
So, first we find the vertex of parabola.
For equation:
For given equation, a=-3 and b=12
Therefore,
Hence, The line of symmetry of given parabola is x=2
