The area of any circle is equal to

, where r is the radius.
We know that the diameter is 12. The radius is always half of the diameter, so the radius of our circle must be 6.
Substitute 6 for r in our equation and simplify.
π6² = π6×6 =
36π in²

x +5
x + 7
x + x + 5 + x + 7 = 21
3 x = 21 - 12
3 x = 9
x = 3
