Find the circumference of the circle. Use 3.14 for pi. Round to the nearest unit.
The circle has a line going through the center and under the line it says: 21 cm.
A 24
B 66
C 125
D 69
Please help my mother will *aliven't* me if I get a bad grade T -T
I love midoriya
I think the answer is A. 24 but im not sure -.-
same @Ash
The circumference of a circle is pi*diameter. The line through the center with 21 cm means the diameter (d) is 21 cm. I don't think the answer is A.
Helppp
To find the circumference of a circle, you can use the formula: circumference = 2 * pi * radius.
Given that the line going through the center of the circle has a length of 21 cm, we can determine that this is the radius of the circle.
Substituting the value of the radius into the formula, we get: circumference = 2 * 3.14 * 21.
Multiplying the values together, we have: circumference = 6.28 * 21.
Calculating the result, we find: circumference ≈ 131.88.
Since we need to round to the nearest unit, the circumference of the circle is approximately 132 cm.
Therefore, the correct answer is option C: 125.
