The answer is <span>$494.55</span>

Let's first imagine a circle and calculate its area and then reduce it in half for the area of a semi-circle. Since this opening is above <span>a 30-inch wide door, the circle will have a diameter of 30 inches.
The area of the circle (A) is:
A = </span>π · r²
where:
π = 3.14
r - radius: r = diameter ÷ 2 = 30 ÷ 2 = 15 inches

So, the area of the circle is:
A = π · r² = 3.14 · 15² = 706.5 inches²

The area of the semicircle is half of the area of the circle:
A1 = A ÷ 2 = 706.5 ÷ 2 = 353.25 inches²

Since  the stained glass window costs $1.40 <span>per square inch, for 353.25 square inches it will cost $494.55:
353.25 square inches * 1.40 $/square inch = $494.55</span>

tiny-mole [99]

Answer:

The volume of the prism is 27 cubic inches.

Step-by-step explanation:

In order to calculate the volume of the given prism, we need to apply the correct formula. The volume of the wedge prism is given by the following formula:

Volume = \frac{1}{2}*b*h*l

Applying the data from the problem on the equation above, we have:

Volume = \frac{1}{2}*6*4.5*2\\Volume = 6*4.5\\Volume = 27

The volume of the prism is 27 cubic inches.

postnew [5]
We have to know divide the total meters that has been traveled by the tortoise which is for 4.8 meters to the time it was completed which is 3 minutes. The formula for speed is: [ speed = distance/time ]. So the equation will be 4.8 meters/3 minutes = 1.6 meters per minute. The speed of the tortoise is 1.6 meters per minute.
