In the diagram, the radius of the outer circle is
2x cm and the radius of the inside circle is 6
cm. The area of the shaded region is
2207 cm
What is the value of x?
Enter your answer in the box.

the area of a circle is πr²

the outer circle area = π 4x²

the inside circle area = π.6²=36π

the outer circle area - the inside circle area = he shaded region

π 4x² - 36π =220π cm2 it implies x²-9 =55 and x²=64, and x =sqrt(64)=8

the value of x is 8

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice
