Answer:
2^2 * 3 * 7
Step-by-step explanation:
First, divide by 2.
84 / 2 = 42
Divide by 2 again!
42 / 2 = 21
21 is divisible by 3, so divide by 3.
21 / 3 = 7
7 is prime, so we've reached the end of our little adventure!
84 = 2 * 2 * 3 * 7, or in exponents, 2^2 * 3 * 7.
Hope that helps!

Answer:
40.192 centimeters
Step-by-step explanation:
The circumference of a circle can be found using:
c= pi* diameter
First, we must find the diameter. The diameter of a circle is twice it’s radius.
d=2*radius
The radius of the circle is 6.4 centimeters. Substitute 6.4 for the radius.
d=2*6.4
d=12.8
Now we know the diameter. We can substitute 12.8 for diameter in the circumference equation.
c=pi*diameter
c=pi*12.8
We also know we are using 3.14 for pi, so we can substitute 3.14 for pi.
c=3.14*12.8
c=40.192
Use appropriate units: centimeters
c=40.192 centimeters
The circumference is 40.192 centimeters.
