Concrete can be purchased by the cubic yard. how much will it cost to pour a circular slab 18 ft in diameter by 3 in. for a patio if the concrete costs $40.00 per cubic yard?

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 ,

Now 1 cubic yard = 27 cubic feet

Therefore volume ,

=> cost of concrete ,

Thus cost of concrete to pour the circular slab is $ 94.25

step-by-step explanation:

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
