Step-by-step explanation:

Given

Cost of white-washing =Rs. 4989.60

Rate =20 per meter square

So, inside area of = $\dfrac{4989.60}{20}=249.48\ m^2$

The surface area of dome= $4\pi\ r^2=249.48$

$4\times 3.142\times r^2=249.48\\r^2=\frac{249.48}{4\times 3.142}=19.85\\r=4.455\ m$

The volume of air in the dome $V=\frac{4}{3}\pi r^3$

$V=\frac{4}{3}\cdot 3.142\cdot (4.45)^3\\V=369.17\ m^3$

Solve the equation 1.5y < -6.75

finlep [7]

1.5y < -6.75

First, divide both sides by '1.5'.
$\frac{-6.5}{1.5}$
Second, since 4.5 × 1.5 = 6.5, simplify the fraction to '-4.5'
$y \ \textless \ -4.5$

Answer: y < -4.5
