If R = 10 cm and r =4 cm then find the area of the ring ​

Answer»

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.
