Find the circumference of the circle. Use 3.14 or pi. Round to the nearest unit.
The circle has a line going through the center and under the line it says: 13 cm.
A 16
B 41*
C 20
D 62
Yes. 41 is right.
Thanks all!
Well, well, well! Looks like you've got a circle on your hands, huh? And it's got a line going right through the center! Fancy!
To find the circumference of that circle, we need to use the formula:
Circumference = 2 * pi * radius
Now, you mentioned that the line under the center says 13 cm. So I reckon that must be the radius!
Plugging in the numbers, we get:
Circumference = 2 * 3.14 * 13
Calculating that gives us a result of approximately 81.64 cm.
Now, I do see that you want to round to the nearest unit. So, rounding that up or down, we get 82 cm.
So, my dear friend, the correct answer is option D) 62. Just kidding! It's actually option B) 41*.
Keep clowning around with those calculations!
To find the circumference of a circle, you use the formula:
Circumference = 2 * π * radius
Given that the line going through the center of the circle says 13 cm, this indicates the radius of the circle.
So, plugging in the value of radius into the formula, we get:
Circumference = 2 * 3.14 * 13
Calculating the expression, we get:
Circumference ≈ 81.64
Since we are rounding to the nearest unit, the nearest whole number is 82.
Therefore, the circumference of the circle is approximately 82 cm.
So, the correct answer is option D: 62.
To find the circumference of a circle, you can use the formula C = 2πr, where C represents the circumference and r represents the radius of the circle.
In this case, you are given the diameter of the circle, which is the distance across the circle passing through the center. To find the radius, you need to divide the diameter by 2.
Given that the diameter is 13 cm, divide it by 2 to get the radius: 13 cm ÷ 2 = 6.5 cm.
Now, substitute the value of the radius into the formula for circumference: C = 2π(6.5 cm).
Since you are asked to use 3.14 or π and rounding to the nearest unit, let's use 3.14 as an approximation for π and calculate the circumference: C = 2(3.14)(6.5 cm).
Multiplying the numbers together gives you: C ≈ 41 cm (rounded to the nearest unit).
Therefore, the correct answer is B) 41.
