The relation between diameter and radius has a relation as under -
Diameter = 2 × Radius.
So, radius is half of diameter and diameter is twice of radius.
The formula for circumference of circle = 2πr, here r represents radius.
The other formula for circumference will be = dπ, where d represents diameter.
Thus, the correct statements will be -
<u>A. The radius is half of the length of diameter.</u>
<u>C. The circumference is the perimeter of circle</u>
<u>D. To find the circumference, multiply diameter with pi.</u>
