Question

Radii of the circles are given below, find their areas.
(1) 28 cm
(2) 10.5 cm
(3) 17.5 cm

Solution

(1) 28 cm

Ar = πr² = π x (28)² 

     = `22/7 xx 28 xx 28`

    = 2464 sq cm

(2) 10.5 cm

Ar = πr² = π x (10.5)² 

     = `22/7 xx 10.5 xx 10.5`

    = 346.5 sq cm

(3) 17.5 cm

Ar = πr² = π x (17.5)² 

     = `22/7 xx 17.5 xx 17.5`

    = 962.5 sq cm

  Is there an error in this question or solution?
