Answer:
14π
Step-by-step explanation:
The equation for circumference is
C = π* diameter
AB is the diameter, so the circumference is 14π

Answer: angle EFB = 35 degrees
========================================================
Explanation:
To get angle EFC, we will average the two arc measures given
This means we add them up and divide by 2
angle EFC = (arcEC + arcBD)/2
angle EFC = (164+126)/2
angle EFC = 290/2
angle EFC = 145
Then we can say:
(angle EFB)+(angle EFC) = 180 ... the two angles are supplementary
(angle EFB) + (145) = 180
angle EFB = 180-145
angle EFB = 35
Using a calculator with the binompdf and binomcdf features, I can calculate these values. My calculator is a TI-83 plus, and the features are found under the 2nd, Vars keys (Scroll up or down until you see them).
If "exactly" is to be found, use binompdf:
binompdf(number of trials, probability of success, exactly number)
ANSWER for exactly 3: binompdf(8, 0.5, 3) = 0.21875 = 21.875%
If "at least" is to be found, use binomcdf:
binomcdf(number of trials, probability of success, at least number - 1)
ANSWER for at least 6: binomcdf(8, 1/2, 5) ≈ 0.8555 ≈ 85.55%
If "at most" is to be found, use binomcdf:
binomcdf(number of trials, probability of success, at most number)
ANSWER for at most 3: binomcdf(8, 0.5, 3) ≈ 0.3633 ≈ 36.33%
