Answer:
If the mean of four numbers is 7, we know that their sum is 7 * 4 = 28. We can use this information to find the last number. If the fourth number is x, we can write:
2 + 5 + 17 + x = 28
24 + x = 28
x = 4
Answer:
9.43km
Step-by-step explanation:
Length of an arc = 2πr(Ф/360)= 2 x 22/7 x 3 x (180/360)
2 x22/7 x 3 x 1/2 = 22/7 x 3 = 66/7 = 9.42857142857≈9.43
