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

d

step-by-step explanation:

d

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
