A circular marble tabletop has a diameter of 42 inches. If the tabletop costs $280, what is the price per square inch?
$0.05
$0.20
$4.25
$4.95
ok so i did division 42 divided by 280=0.15 im still lost
Are you just randomly dividing numbers you see in the question?
diameter = 42 inches
so radius = 21 inches
area = π(21)^2 = appr 1385.44 square inches
price per square inches
= $280/1385.44 inches^2
= $0.20 / inch^2
whats the anser????????????

To find the price per square inch, we need to calculate the area of the circular tabletop and then divide the total cost by that area.
The formula to calculate the area of a circle is A = π * r^2, where A is the area and r is the radius. Since we are given the diameter of the tabletop (42 inches), we can find the radius by dividing the diameter by 2.
Radius (r) = Diameter / 2
r = 42 / 2
r = 21 inches
Now that we have the radius, we can calculate the area of the tabletop.
A = π * r^2
A = π * 21^2
A = π * 441
A ≈ 1385.44 square inches (Using π ≈ 3.14)
To find the price per square inch, we divide the total cost by the area.
Price per square inch = Total cost / Area
Price per square inch = $280 / 1385.44
Price per square inch ≈ $0.20
Therefore, the price per square inch for the circular marble tabletop is $0.20.
So the correct answer is:
$0.20
How about showing me some effort on your part, I have done of them for you so far.
You know the formula for the area of a circle, so go for it
