Question

The radius of a circular pond is 1.4m. the radius of another circular pond whose area is 1/4 of the area of this pond

Answer 1

Answer:

Step-by-step explanation:

Area of the circular pond = ℼ (r1) (r1)

                                         = ℼ (1.4) (1.4)

Area of the pond required = 1/4 ( ℼ (1.4) (1.4))

                 ℼ (r2) (r2) =  ℼ (1.4) (1.4) 1/4

                    (r2) (r2) =    (1.4) (1.4) 1/4

                     (r2)       =    (1.4) (1/2)

                     (r2)       =     (0.7) m = 70 cm
