Answer:
200.96
Step-by-step explanation:
Radius is 8 since the diameter is 16, radius is half the diameter.
Multiply 3.14 (pie) to 8^2(64) and thats your answer!
After multiplication, the equation would be :
6x2 + 10x2 - 14x - 15x2 - 25x + 35
= x2 - 29x + 35
we have
This is a quadratic equation (vertical parabola) open up
so
the axis of symmetry is the coordinate x of the vertex
<u>Find the vertex of the function</u>
the vertex is the point--------->
so
the axis of symmetry is
therefore
the answer in the attached figure
12^2 +b^2 = 20^2 because of the Pythagorean theorem
144 + b^2 =400
B^2 =256
B=16
