If the area of a circle is 25pi (n), what is the radius of the circle

5

Step-by-step explanation:

the are is pi times radius times radius

so do the square root of 25, which is 5.

this means that the radius is 5

five (5).

Step-by-step explanation:

Area of circle =pi r^2

given that area is 25pi

now equate both we get

25pi=pi r^2

25=r^2

r=5

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3
