Answer:
1308.02cm^2
Step-by-step explanation:
Finding Radius = D/2
40.82/2 = 20.41 centimetres
Finding Area of a circle
E = πr^2
= 3.14 x 20.41^2
= 416.57 π
= π x 416.5681 = 1308.02cm^2
Answer:
B) 1
Step-by-step explanation:
Since we are using elimination, we can just cancel 2y and -2y. No need of multiplying anything if we are just looking for x.
We add the equations and get:
9x=9
Then divide and the final answer is:
x=1

Answer:
median = 17.5
Step-by-step explanation:
The median is the middle value of a data set arranged in ascending order. If there is not a middle value then the median is the average value of the numbers either side of the middle.
Data in ascending order is
8, 15, 17, 18, 19, 21
The median is between 17 and 18, hence
median =
= 17.5
The function of 5 (or y when x is 5) can not be determined with this little information.
