if the circumference of a circle is equal to 24cm what is the radius
2 pi r = 24
r = 12/pi
Study
The formula to calculate the circumference of a circle is C = 2πr, where C represents the circumference and r represents the radius.
In this case, we are given that the circumference is 24 cm.
Plugging this value into the formula, we get:
24 = 2πr
To solve for r, divide both sides of the equation by 2π:
r = 24 / (2π)
Calculating the value, we find that the radius is approximately 3.82 cm.
To find the radius of a circle when given the circumference, you can use the formula:
Circumference = 2πr
where 'Circumference' is the given value (24cm) and 'r' is the radius we are trying to find.
Rearranging the formula to solve for 'r':
r = Circumference / (2π)
Now let's substitute the value of the circumference into the formula and calculate the radius:
r = 24cm / (2 * 3.14)
r ≈ 3.82 cm
Therefore, the radius of the circle is approximately 3.82 cm.
