A circular plate has circumference 32.7 inches. What is the area of this plate? Use 3.14 for pie.
1 answer:
Answer: 85.13
Step-by-step explanation:
We know:
Circumference = 2*3.14r
Area of a circle = 3.14r²
We need to find the radius given the circumference before solving for the area:
32.7 = 2*3.14r
32.7/6.28 = 6.28r/6.28
r = 5.20700637
Now that we know the radius, we can plug it in to find the area:
A = 3.14(5.20700637)²
A = 3.14(27.1129153)
A = 85.134554

Answer:
Step-by-step explanation:
Answer:
lower price = 3
higher price =11
Step-by-step explanation:
p(x) = -2(x-3) (x-11)
Setting equal to zero
0 = -2(x-3) (x-11)
Using the zero product property
x-3 = 0 x-11 =0
x=3 x = 11
