Renae needs to put trim around a circular tablecloth with a diameter of 36 inches. Use the equation C=PId to find three sets of approximations for the amount of trim she will need. Truncate the value of PI to the to the ones,tens, and hundredths place. Then determine how much trim she should buy.
C = 3 * 36
C = 3.1 * 36
C = 3.14 * 36
How much trim should she buy? Remember you have to round it to the next inch.
To find the approximate amount of trim Renae will need to put around the circular tablecloth, we can use the formula:
C = πd
where C represents the circumference of the circle, d represents the diameter, and π is a mathematical constant approximately equal to 3.14159.
Given that the diameter of the tablecloth is 36 inches, we can plug this value into the equation:
C = π * 36
Now, let's calculate the approximate amount of trim needed using different approximations of the value of π:
1. Truncating π to the ones place (3.14):
C ≈ 3.14 * 36 = 113.04 inches
2. Truncating π to the tens place (3.1):
C ≈ 3.1 * 36 = 111.6 inches
3. Truncating π to the hundredths place (3.14):
C ≈ 3.14 * 36 = 113.04 inches
Therefore, Renae will need approximately 113.04 inches, 111.6 inches, or 113.04 inches of trim, depending on the level of approximation used for π.
To determine how much trim she should buy, it would be advisable to round up to the nearest whole inch to ensure she has enough. So Renae should buy at least 114 inches, 112 inches, or 114 inches of trim, respectively, for the three different approximations of π.
