Find the cost of polishing a circular table top of diameter 2.2m if the rate of polishing is 20 per m sq

Answer»

Answer:

75.988/-

Step-by-step EXPLANATION:

TOTAL AREA to be polished=area of CIRCULAR table

area of CIRCLE = πr²

2r=diameter

2r=2.2

r=2.2/2

r=1.1

area = 3.14 × (1.1)²

= 3.14×1.21

= 3.7994m²

1m²=20/-

3.7994 = (?)

3.7994×20 = 75.988/-
