We need to know the dimension of the paving stone.
For example, the paving stone is shaped like a rectangular prism with the following dimension.
Length = 10 inches
Width = 3 inches
Height = 2 inches
Volume of a rectangular prism = Length * Width * Height
V = 10 in * 3 in * 2 in
V = 60 in³
60 in³ / 4 in³ = 15
cost of paving stone = 2.50 + .18(15) = 2.50 + 2.7 = 5.20 per paving stone.
Assuming you're working in base 10, then the antilog of 3.493 is equal to 10^3.493 = 3,111.71633710601
This rounds to 3111.7163 so the answer is choice D
Answer:
y stands for unknown number
Step-by-step explanation:
The problem ask to find the are of the shaded region of the circle which has a radius of 12cm. The are of the circle is computed as the formula of pie times the square of the radius so the are of the circle would be 452.389 cm2 and the area of the shaded region would be 150.796 cm2^2.

Given:
In ΔHIJ, h = 40 cm, ∠J=20° and ∠H=93°.
To find:
The length of j, to the nearest centimeter.
Solution:
According to Law of sine,

In ΔHIJ, using law of sine, we get



On further simplification, we get



Approximate the value to the nearest centimeter.

Therefore, the length of j is 14 cm.
