Answer:
k = 3.
Step-by-step explanation:
By the factor theorem if p - 1 is a factor the f(1) = 0.
So f(1) = (1)^4+1^2+1-k = 0
1 + 1 + 1 - k = 0
3 = k.
Where’s the angle? Is there a picture of it?

</span>Find Radius
------------------------------------
Radius = Diameter ÷ 2
Radius = 27 ÷ 2
Radius = 13.5 cm
------------------------------------
Find Area
------------------------------------
Area of circle x = πr²
Area of circle x = 3.14 x 13.5²
Area of circle x = 572.265 cm²
------------------------------------
Find Radius
------------------------------------
Radius = Diameter ÷ 2
Radius = 12 ÷ 2
Radius = 6 cm
------------------------------------
Find Area
------------------------------------
Area of circle y = πr²
Area of circle y = 3.14 x 6²
Area of circle y = 113.04 cm²
------------------------------------
Compare the area
------------------------------------
572.265 - 113.04 = 459.23 cm²
------------------------------------------------------------------------
Answer: Circle x is 459.23cm² greater than circle y.

The congruence symbol is this: ≅.
It’s saying to write the statement that’s saying both shapes are congruent. For example ABC ≅ DEF but use the letters in the shapes they gave.
