Since the circles are concentric so they have common centre.
Distance between them is given by formula-
R₁-R₂ where R₁≥R₂
So distance between them=14cm-7cm=7cm
So π14²-π7²=π147=462 cm²

We know that area of circle with radii 14cm = pi * r * r
= 3.14 * 14 * 14
= 616
Area of circle with radii 7cm = pi * r * r
= 3.14 * 7 * 7
= 154
Area of space between them = 616 - 154
= 462 cm.
Hope this helps!
