The area of a circle is 49π 〖"cm" 〗^2. find the circumference of the circle. (note: make sure you are showing the formulas you use to answer the question and how the numbers fit into the formulas).

C = 14*pi   cm

Step-by-step explanation:

The area of a circle is given by A = pi * r^2

We know the area is 49 pi

49 pi = pi r^2

Divide each side by pi

49 pi/pi = pi/pi r^2

49 = r^2

Take the square root of each side

sqrt(49) = sqrt(r^2)

7 = r

Now we need to find the circumference

C = 2*pi*r

C = 2 *pi *(7)

C = 14*pi   cm

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
