Answer:

A = 156.25 pi  cm^2

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi *r

25 pi = 2 * pi *r

Divide each side by 2 pi

25 pi/2 pi  = 2 pi r / 2 pi

12.5 = r

We can find the area by

A = pi r^2

A = pi ( 12.5) ^2

A = 156.25 pi  cm^2

3/4(8x-4)=7x+2, I need to find out the answer
laiz [17]

Answer: x = -5

Step-by-step explanation:

First convert 3/4 to decimal= 0.75

0.75 (8x - 4) = 7x + 2

6x - 3 = 7x + 2

Transpose 7x from right hand side to the left hand side

6x - 7x = 2 + 3

-x = 5

x = -5

I hope this helps.
