Answer: Thus cost of concrete to pour the circular slab is $ 94.25
Step-by-step explanation:
Given
Diameter of circular slab, d=18 ft
Thickness of slab , t= 3 inches = 0.25 ft
Rate of concrete , R = $40.00 per cubic yard
Volume of the slab , [tex]V=\frac{\pi d^{2}t}{4}=\frac{\pi \times 18^{2}\times 0.25}{4} ft^{3}=63.6 ft^{3}[/tex]
Now 1 cubic yard = 27 cubic feet
Therefore volume , [tex]V=63.6 ft^{3}=\frac{63.6}{27}yard^{3}=2.356yard^{3}[/tex]
=> cost of concrete , [tex]C=V\times R=\$ 2.356\times 40=\$ 94.25[/tex]
Thus cost of concrete to pour the circular slab is $ 94.25
