The circumference of a circle is 15n cm what is the area of the circle in terms of n

Area of circle is

Step-by-step explanation:

Formula for circumference of circle is given as,

Given that C = 15 n cm,

Substituting the value,

Solving above equation for r, divide both side by

Simplifying,

Formula for area of circle is given as,

Substituting the value of r,

Squaring the parenthesis,

Cancelling out the common term,

Therefore, area of circle in terms of n is

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

42
