The radius of a circle is 33 feet. What is the circle's circumference?
The radius of a circle is 33 feet. What is the circle's circumference?
The circumference is :
↬ 207.24 ft
Solution:
To calculate the circumference, we will use the formula C = 2πr.
- C = Circumference
- π = 3.14
- r = radius

Now plug in the values. We shouldn't forget to use 3.14 for pi.
[tex]\bold{Circumference = 2 \times 3.14 \times 33}[/tex]
[tex]\bold{Circumference = 6.28 \times 33}[/tex]
[tex]\bold{Circumference = 207.24\:ft}[/tex]
Hence, the circumference is 207.24 ft
If the radius of a circle is 33 feet, the circle's circumference is 207.24 feet.
Given: Radius of a circle, r = 33 feet
and taking π = 3.14
The circumference of the circle can be calculated using the formula,
C = 2πr.......(i)
where, C ⇒ circumference of a circle, and
r ⇒ radius of a circle
Therefore, putting the given values in equation (i), we get,
C = 2 x 3.14 x 33
⇒ C = 207.24 feet
Thus, if the radius of a circle is 33 feet, the circle's circumference is 207.24 feet.
