The circumference of the circle to one decimal place is 47.1cm
The circumference of a circle is the outer bound of a cricle . it can also be said to be the perimeter of a circle.
The circumference of a circle is expressed as;
circumference = 2πr
where r is the radius of the circle.
Since the diameter is 15cm
radius = diameter/2
radius = 15/2
= 7.5
Circumference = 2 × 3.14 × 7.5
= 47.1
Therefore, the circumference of the circle is 47.1cm
