Answer:
9.42
Step-by-step explanation:
The circumference of a circle is calculated using the following formula:
C=2πr (C: circumference, r : radius)
radius here is 6 and π is given as 3.14
2*(3.14)*6 = 18.84 now divide this by 2 to find the length of semicircle
18.84/2 = 9.42
Answer, Step-by-step explanation:
According to the exercise, we evaluate the delivery time of a courier company and we will hypothesize the best case with a sample size of 10, which is:
Small sample T test for single mean
The hypothesis that we will develop will be the following:
null hypothesis = mu> = 6
hypothesis alternativa: <6
Okay so the answer would be
You use the formula C=2(3.14)r r is the radius and in this situation 2 so the answer will be 12.56
