Hello, could someone please go over the steps for this question? Thank you!
1. Find the circumference. Leave your answer in terms of pi.
The middle line going through the circle is 8.4
(I'm so sorry I don't know the name of the line, brain fart).
A) 12.6 pi cm
B) 4.2 pi cm
C) 16.8 pi cm
D) 8.4 pi cm
So I know that Ms. Sue was going over this with me (thank you so much by the way)! But i'm still quite confused on how to do this problem.
Ms. Sue gave me the formula 8.4 pi, would that be the answer since, c=d pi?
I am so sorry if that was the whole thing and I didn't get it until now!
yes, circumference = pi D
= 8.4 pi
8.4 p
No problem! Let's go over the steps to solve this problem.
The circumference of a circle can be found using the formula: C = πd, where C is the circumference and d is the diameter of the circle.
In this case, you have the middle line going through the circle, which is the diameter. The diameter is given as 8.4 (presumably in units of length, like centimeters).
To find the circumference, you need to multiply the diameter by π (pi). So, the calculation would be: C = π * 8.4.
Now, let's evaluate this expression:
C = π * 8.4 ≈ 26.3893 (approximately)
Since the question asks to leave the answer in terms of pi, we will use the approximation of π (pi) as 3.14.
C ≈ 26.3893 ≈ 26.4 (rounded to one decimal place)
So, the approximate circumference is 26.4 units.
Now, let's look at the answer choices:
A) 12.6 pi cm
B) 4.2 pi cm
C) 16.8 pi cm
D) 8.4 pi cm
Since we found that the approximate circumference is 26.4, and the answer choices are all in terms of pi, we need to find the closest option.
Option A) 12.6 pi cm is not close to 26.4.
Option B) 4.2 pi cm is not close to 26.4.
Option C) 16.8 pi cm is not close to 26.4.
Option D) 8.4 pi cm is close to 26.4.
Therefore, the most accurate answer is D) 8.4 pi cm.
I hope that clears up the steps for this problem. Let me know if you have any further questions!
