rose is getting a snare drum for her birthday! They are 14 inches in diameter. I want to wrap ribbon around 4 times. How many inches of ribbon do i need? write the formula, and show your work.
d = Diameter
P = Perimeter
P = d * pi = 14 * pi
4 P = 4 * 14 * pi = 56 pi = 56 * 3.14159 = 175.92904 in
approx. 176 in
Thanks so much!:-)
To calculate the total length of ribbon needed to wrap around the snare drum four times, you can use the formula:
Total length of ribbon needed = Circumference of the snare drum × Number of wraps
First, let's calculate the circumference of the snare drum using its diameter. The formula for the circumference of a circle is:
Circumference = π × Diameter
The value of π (pi) is approximately 3.14.
Given that the diameter of the snare drum is 14 inches, we can calculate the circumference as follows:
Circumference = 3.14 × 14
Circumference = 43.96 inches (rounded to two decimal places)
Now, we can calculate the total length of ribbon needed:
Total length of ribbon needed = 43.96 inches × 4
Total length of ribbon needed = 175.84 inches (rounded to two decimal places)
Therefore, you would need approximately 175.84 inches of ribbon to wrap around the snare drum four times.
Note: When wrapping ribbon around an object, there might be some overlapping or excess ribbon used, so it's always good to have a slightly longer length than the calculated value to ensure you have enough ribbon to wrap around.
