The circumference of f is 109.71
To get the circumference
The circumference of a circle is the total length around the outer boundary or perimeter of the circle. It is calculated using the formula:
Circumference = π × diameter
or equivalently,
Circumference = 2 × π × radius
we have
64 / 210 = x / 360
we have to cross multiply
x = 768 / 7
= 109.71
The circumference of f is 109.71
