Answer:
21.07
Step-by-step explanation:
This problem is a 2-step process. First you have to find the distance between the two points on the circle, using the formula , which would give you the diameter. After the diameter is found, using the formula C=πd, the circumference can be found.
Using the points (1,7) and (-2,1), we can find the diameter of the circle by plugging it into the first equation.
d=\sqrt{((1--2)^2+(7-1)^2}
After plugging that into a calculator, we can find that the diameter is approximately equal to 6.71.
Now 6.71 can be plugged into the equation C=πd to find the circumference.
C=πd
C=π*6.71
<u>C≈21.07 units</u>
Answer:
3 rooms
Step-by-step explanation:
2x = 5
x = 5/2
5/2 = 7.5/x
5x = 15
x = 3
Answer: m=9
Step-by-step explanation: add 16 to both sides, Which gives you 36.Now you have 4m=36 ,so you divide 4 on both sides which gives you 9 .So it is m=4
160cm3
2/5 - 1/4 = 8/20 - 5/20 = 3/20
(3/20)t = 24
t = 160
