Answer:
C=401.92
Step-by-step explanation:
the equation for area of a circle is A=r^2 pi so if the area of this circle is A=64^2 pi, then we can see that 64 is the radius of the circle.
(A=r^2 pi
A=64^2 pi so r=64)
So if the radius is 64, then the diameter is (because diameter is double the radius) Then we use the newfound diameter and plug into the equation for Circumference of a circle which is
C=d pi
C=128 (3.14)
so C=401.92
Hope this helps! :)
Answer:
is 36(x) im not sure if x should be there
Step-by-step explanation:
I am not sure but i hope it's right
f(x)=5x+21x^2-21x-5;x+5 first you simplify
F(x)=6x^2
F(x)=36
12 for $25 is $2.08 per each. 24 for $46 is $1.90 per each. 50 for $94 is $1.90 per each.
