Question

a circular plot is of radius 77 M find its value at rupees 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.32,59,637.50

Answer 2

Correct Question:

A circular plot is of radius 77 m. Find value of ( levelling, paving, etc. ) at ₹ 175 per square metre.

• I have used the words in bracket because I do not know what actually is being done on the plot. Anyways, it won't affect our answer.

₹ 3260950


$\small{\boxed{\boxed{\bold{Perfect\: Explanation:}}}}$

Radius of circular plot, r = 77 m

We know that area of a circle is equal to the product of pi and square of radius.

Area of the plot, A = π * ( r ) ^ 2
A = π * ( 77 ) ^ 2
A = ( 22 / 7 ) * 77 * 77
A = 22 * 11 * 77
A = 18634 sq. m
Area of the plot = 18634 sq. m

Rate of doing the work = ₹ 175 / sq. m

Cost of doing the work = 18634 * ₹ 175
Cost of doing the work = ₹ 3260950
