Answer:
Chord 12 cm long subtends an angle of 40 degrees at the center of a circle.
θ= 40° = 0.698 rad
Let R be the radius of circle.
Chord Length = 2Rsin(θ/2)
12=2R sin (0.698 /2)
R= 17.54
Ans: Radius of circle = 17.54 cm
Answer:
1.5
Step-by-step explanation:
To find the mean, we must add all of our terms, and then divide by the number of terms.

Solve:

Since we have seven terms, we must divide our total (
), by seven.
÷ 
Solve:
÷ 
Therefore, the mean is
