Joanna is selling cheese at the farmers market one wheel and cheese has a diameter of 9 in what is the area of the wheel of cheese use 3.14 for π
____Square inches
If the nine inch wheel of cheese cost $18.60what is the cost per square inch if the cost is less than a dollar put a zero to the left of the decimal point.
$____ per square inch
so what are the two answers
To find the area of a circular wheel of cheese, we can use the formula:
Area = π * (radius)^2
In this case, the given information is the diameter of the wheel, which is 9 inches. The radius is half the diameter, so the radius of the wheel is 9/2 = 4.5 inches.
Now, let's calculate the area using the formula:
Area = 3.14 * (4.5)^2
Area = 3.14 * 20.25
Area ≈ 63.585 square inches (rounded to three decimal places)
Therefore, the area of the wheel of cheese is approximately 63.585 square inches.
Next, to find the cost per square inch, we need to divide the cost of the wheel of cheese ($18.60) by the area (63.585 square inches):
Cost per square inch = Total cost / Area
Cost per square inch = 18.60 / 63.585
Cost per square inch ≈ $0.293 (rounded to three decimal places)
Hence, the cost per square inch of cheese is approximately $0.293.
well pi is 3.14159265359
R = 9/2 = 4.5 inches radius
area = 3.14 * 4.5^2
18.6 dollars / area from part A
