Answer:
Area = 2200/7cm2
Area = 352/7cm2
Step-by-step explanation:
If we take R = 10
Area of ring = πR2
= 22/7 ×(10)^2
= 22/7 × 100
= 2200/7 cm2
If we take R = 4cm
Area of ring = πR2
= 22/7 × (4)^2
= 22/7 × 16.
= 352/7 cm2
Hope it helps you.

Area of the circular ring=π(R²-r²)
=22/7(10²-4²)
=22/7(100-16)
=22/7(84)
=264
