Answer:
Step-by-step explanation:
The formula for determining the area of a circle is expressed as
Area = πr²
Where
π is a constant whose value is 3.14
r represents the radius of the circle.
Considering the inner layer
radius = 2 millimeters
Area of base = 3.14 × 2² = 12.56 mm²
Considering the outer layer,
Radius = 6 mm
Area of base = 3.14 × 6² = 113.04 mm²
Percent of the area of the base of the outer layer that is the area of the base of the inner layer is
12.56/113.04 × 100 = 11.1%
Answer: D, All of the above

Answer:
The prince's crown had a greater ratio of red gems to purple gems.
Step-by-step explanation:
KING = 5 red / 8 purple
PRINCE = 4 red / 5 purple
Times the ratio for the king by 5
5(5) / 8(5) = 25/40
Times the ratio for the prince by 8
4(8) / 5(8) = 32/40
The prince has a greater ratio of red gems
Hope this is right, and sorry if it is incorrect. Have a good day!

Step-by-step explanation:
I can not exactly show a graph, but the equation will be y=1/4x-1, since:
Points: (4,0) (0, -1)
Slope: (0+1)/(4-0)= 1/4
Slope intercept form: y=mx+d
