Hello!
The formula to find the circumference of a circle is:
C = 2πr or C = πD
We know what the radius of the circle is, and in order to find the circumference, we first need to use this to find the diameter. The formula for the diameter of a circle is:
radius x 2
In this case, the diameter is:
46 x 2 = 92
Now, we can plug this number into the formula C = πD:
C = 92π
C = 288.88
The circumference of a circle with the radius of 46 is 288.88.
I hope this helps you! Have a lovely day!
