Answer:
200.96
Step-by-step explanation:
The circumference is
C = 2*pi*r
50.24 = 2 * 3.14 (r)
50.24 = 6.28 r
Divide each side by 6.28
50.24/6.28 = r
8 =r
We want to find the area
A = pi r^2
A = 3.14 (8)^2
A =200.96
Answer:
The solution set represented by the following graph is:
{x | x∈ R, x < -2}
Step-by-step explanation:
Clearly from the figure we could see that the solution set is to the left of ' -2' and excluding the point '-2' since there is a open circle at -2.
This means that -2 is not included in the set.
Also in interval; form the set of points that belong to the solution set are:
(-∞,-2)
in set-builder form it is written as:
{x | x∈ R, x < -2}
Answer:
see below
Step-by-step explanation:
f(x)= -(x-2)^2 +4
This is the vertex form of the equation for a parabola
y= a ( x-h)^2 +k where (x,k) is the vertex of the parabola
a = -1 h= 2 k = 4
The vertex is ( 2,4)
