Answer:
D. 314 yds
Step-by-step explanation:
Given:
Diameter = 100 yds
Required;
Circumference of the circle
Solution:
Circumference of circle = πd
Plug in the value
Circumference = π × 100
= 314 yds (nearest whole number)
check the picture below. You can pretty much just count the units from the grid.
How many slices did each person have?
Answer: 125lb < M < 155 lb
Step-by-step explanation:
The mean mass is 140 lb, and the deviation must be less than 15 pounds (exactly 15 is not accepted).
Then (140lb + 15lb) is not alowed, and (140lb - 15lb) is not alowed.
Then we can define M = mass.
We have the two equations:
M < 140lb + 15lb
M < 155lb
And
M > (140lb - 15lb)
M > 125lb
If we write these two relations togheter, we get:
125lb < M < 155 lb
