a. 15.7units
b. 31.4 units
c. 62.8 units
d. 78.5 units
Answered by Steve
use the distance formula to find the length of the diameter.

Then, C = πd
Answered by Deez
Use distance formula or Pythagorean theorem.
Pythagorean-
6^2+8^2= radius^2
100= radius^2
10= radius
radius= r

Use circumference formula.
C=2pir
C=2pi10
C=62.83
