Question

a circular plot is of radius 77 m. find its value at 175 per square metre

Answer 1

Area of a circle= Π x square of radius 

                        = Π  x 77 x 77 square metre
                        = 18,626.50 square metre
Value per sq.mt. = Rs.175
Therefore value of 18,626.50 sq.mt.= 18,626.50 x 175 = Rs.3,259,637.50

Answer 2

area of a circle = π r² = 22/7 into 77 into 77
22 x 11 x 77 = 18634 sq. m.
cost = 175 per sq. m
so total value = 18634 x 175 =  Rs. 3260950
