Question

please give me answer of this question​

Answer 1

EXPLANATION:-

Area of the pool =πr²

Radius of the pool =10.5 ,So area =

π×(10.5)²

$\sf\;\frac{22}{7}\times(10.5)^2\\\\\frac{22}{7}\times110.25\\\\\frac{22\times110.25}{7}\\\\\frac{2425.5}{7}\\\\346.5$

So the area is 346.5 m²

Now let's calculate the cost:-

Cost =346.5×180

==>62370 rs

So the cost will be 62370 rs
