Solve step by step:
10/2= a/a-9
note: i need this !

10/2= a/a-9

10/2=a/a+-9

Multiply all terms by a and cancel

10a/2 = a+-9a

Simplify both sides of the equation

5a= -8a

Add 8a to both sides

5a+8a= -8a+8a

13a=0

Divide both sides by 13

13a/13=0/13

a= 0

Answer : No solution

I hope that's help !

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
