The arc measurement of the sector is 216°.
Therefore the area of the sector is 216/360 = 0.6 of the area of the entire circle.
Let r = the radius of the circle.
Then the area of the circle is πr².
Therefore the area of the sector is
0.6*πr²
Because the area of the sector is 15π cm², therefore
0.6πr² = 15π
r² = 15/0.6 = 25
r = 5 cm
Answer: 5 cm
Answer:
The correct option is B.
Step-by-step explanation:
It is given that the correlation coefficient between two variables is -0.95.
Correlation coefficient between two variables is denotes by ρ. The value of ρ is leis between -1 to 1.
If , then it represent perfect negative correlation.
If , then it represent perfect positive correlation.
If , then it represent no relationship between the variables.
Since the -0.95 is near to the value -1, therefore we can say that there is a strong negative association between the variables. Option B is correct.
