Answer:
5.5
Step-by-step explanation:
The given circumference is C = 12*pi
The formula for the circumference of any circle, with radius r, is
C = 2*pi*r
Plug in the given value of C and solve for r
C = 2*pi*r
12*pi = 2*pi*r ... C has been replaced with 12*pi
12 = 2*r ... divide both sides by pi (they cancel out)
6 = r ... divide both sides by 2
So r = 6 is the radius
Answer:
d. 32 π
Step-by-step explanation:
As given
Area of circle = 64 π
Area of circumference = 1/2*(Area of circle)
Area of circumference = 1/2*(64π)
Area of circumference = 0.5*64π
Area of circumference = 32π
4% = 0.04
1020 * 0.04 =40.80 ( commission)
450 + 40.80 = $490.80 total pay
