unlikely
Step-by-step explanation:
if it was impossible it would be 0/8
Answer: 28
Step-by-step explanation:
The mean of 15 numbers = 12
Then , the sum of the numbers = 12x15 = 180
Let the extra number included be
, then
The new sum = 
And the new total number will increase from 15 to 16
new mean = 13 , so we have :





therefore , the extra number is 28
Answer:
Step-by-step explanation:
If the sector wasn't there, the area would be that of a circle. The formula for a circle = pi * r^2
But the sector is there and so you have to account for it.
Area sector = (60/360) * pi * 11^2
Area sector = 1/6 * pi * 121
1/6 of 121 = 20.17
Area of sector = 20.17 pi square cm
