Answer:
Therefore it is possible to find the circumference and area of a circle if we are given the radius or diameter of the circle.
Step-by-step explanation:
i) to find the area of a circle or circumference the radius , r, is required.
ii) if we are given the diameter, d. then we have to find the radius, r, by dividing the diameter by 2, that is [tex]d = \frac{r}{2}[/tex].
iii) area of the circle is given by A = [tex]\pi r^{2}[/tex]
iv) circumference of the circle is given by C = [tex]2\pi r[/tex]
Therefore it is possible to find the circumference and area of a circle if we are given the radius or diameter of the circle.
