the outer and inner diameter of a circular ring are 34 cm and 32 cm respectively. The area of the ring is

area of the ring= area of outer circle - area of inner circle= pi (R2-r2
                       =22/7{ (17)2-(16)2}
                       =  22/7 * 33 
                      = 103.714 cm2
hope it helps :)

R = 17 cm , r= 16 cm area of ring = pi (R2- r2) =pi ×1×33. = 3.14 × 33 = 103.62 sq. cm

All these are wrong....

R(outer radius)=34cm r(inner radius)=32cm Area of circular ring =π(R^2 -r^2) = 3.14((34^2)-(32^2)) =3.14(1156-1024) =3.14×132 =414.48 ans

Outer and inner diameter of a circle ring are 34 and 32 respectively then find the area of ring
  • -1
Area of the ring= Area of outer circle - Area of inner circle= pi (R2-r2
                       =22/7{ (17)2-(16)2}​​​​​​​
                       =  22/7 * 33 
                      = 103.714 cm2
Hope it helps you....

Area of ring = Area of outer circle _ Area of inner circle 22 ×((17)^2 _ (16)^2) 7 22 × 33 7 103.714 cm^2
