A conical tomb is made up of bricks each of a front surface area of 5 square meters.The slant height and radius of the tomb are measured to be 25 m and 7 m respectively. The approximate no. of bricks made used to construct the tomb are ___ (Take π=227)
110
Slant height l = 25
Radius r = 7
Curved Surface area of the tomb = πrl
=227×7×25
=550m2
So, No. of bricks required =Curved Surface Area of tombFront Surface Area of brick
=5505=110 bricks
