Answer:
you are looking for the circumference. which is C(circumference)= x r (radius)
the radius is =to half of the diameter.
c=56.55
Step-by-step explanation:
circumference=distance around
C=pid
d=diameter
pi=3.14 approx for t his question
given
diameter=18
C=18*3.14
C=56.52 in
length around is 56.52 inn
Answer:
Plant B
Step-by-step explanation:
The only measure of variation we really need to check is the mean, or average, of tomatoes that each plant produced. This is because if Kathryn was a farmer, she would want a plant that on average, produces more tomatoes. For that reason, in this context, the mode, median and range are irrelevant. To find the mean of a data set, you simply divide the sum of all of the data by the number of data in the set. Therefore:
Mean of Plant A: (4 + 6 + 7 + 3 + 6 + 2 + 1 + 3 + 6 + 5) / 10 = 43 / 10 = 4.3
Mean of Plant B: (5 + 6 + 7 + 6 + 8 + 9 + 6 + 7 + 8 + 9) / 10 = 71 / 10 = 7.1
As you can see, the mean tomatoes Plant B produces is larger than that of Plant A, therefore, Kathryn should choose Plant B if she was a farmer.
Answer:
528 Litres
Step-by-step explanation:
If 5/8 is 330 Litres
you want to work out what 8/8 is
the first step you would take is to find 1/8. you can do this by dividing by 5
therefore 1/8 is 66 Litres (what you do to one side, you must do to the other)
now, you are able to find 8/8. you do this by multiplying both sides by 8
therefore you get 8/8 or 1 whole is 528 Litres
D(1-1/4)
=3/4d
3/4d represents the money saved on a pillow
