Question

find the cost of ploshing a circular table top of diameter 2m,if the rate of ploshing is rupees 10m ^2 (take pie=3.14)​

Answer 1

0.314mper square

Step-by-step explanation:

Diameter=2m

So, the radius is 2\2=1m

Area of circular table=pie rsquare

Let, pie=3.14and r=1m

Put all the values in the formulae, so we get, 3.14*1*1=3.14rsquare

If, the rate of ploshing=10mper square

then the cost for 3.14msquare=3.14*10= 0.314mper square
