To find the next address: If the owner imported 100 square feet of marble to decorate the façade of the house and 13 square feet of scrap was left when construction was completed, how much marble was used? Write and solve an equation
To find the next address: The circular stained glass window on the front of this church is filled with hearts. If the area of one of these hearts is 25 square inches, then find the area of all the hearts.
To find the next address: Find the area to the nearest whole number of a circle with a radius of 4.03 ft. Use 3.14 for Π.
I have literally been working on these for 6 hours and cant figure out these 3... can someone help me please?!
Never mind I figured out number 1 but not the others. :(
Ok I also figured out number 2 but not the last one lol
#3
area of circle = πr^2
= 4.03^2 π = appr 51
Omg thank you soooo much Reiny! :D
Sure, I can help you with these questions. Let's take them one by one:
1. To find the amount of marble used, we need to subtract the amount of scrap left from the total amount imported. Let's call the amount of marble used "M". The equation to solve this problem can be written as follows:
M = 100 square feet (amount of marble imported) - 13 square feet (amount of scrap left)
Therefore, M = 87 square feet (amount of marble used)
2. To find the area of all the hearts on the stained glass window, we need to know the number of hearts in the window. Unfortunately, the question does not provide this information. So without the number of hearts, it is not possible to find the total area of all the hearts.
3. To find the area of a circle, we can use the formula A = πr^2, where A represents the area and r represents the radius. Given that the radius is 4.03 ft, and using the approximation of π = 3.14, we can substitute these values into the formula to find the area:
A = 3.14 (π) * (4.03 ft)^2
A ≈ 3.14 * 16.2409 ft^2
A ≈ 51.05 ft^2 (rounded to the nearest whole number)
I hope this helps! Let me know if you have any further questions.
