Given:
Given that the diameter of the circle is [tex]\frac{7}{2} \ cm[/tex]
We need to determine the radius, circumference in terms of π and circumference using π = 3.14.
Radius:
The radius of the circle can be determined using the formula,
[tex]r=\frac{d}{2}[/tex]
Substituting [tex]d=\frac{7}{2}[/tex], we get;
[tex]r=\frac{(\frac{7}{2})}{2}}[/tex]
Simplifying, we get;
[tex]r=\frac{7}{4} \ cm[/tex]
Thus, the radius of the circle is [tex]\frac{7}{4} \ cm[/tex]
Circumference in terms of π:
The circumference of the circle can be determined using the formula,
[tex]C=2 \pi r[/tex]
Substituting [tex]r=\frac{7}{4} \ cm[/tex], we get;
[tex]C=2 \pi (\frac{7}{4})[/tex]
[tex]C=\frac{7}{2} \pi \ cm[/tex]
Thus, the circumference in terms of π is [tex]\frac{7}{2} \pi \ cm[/tex]
Circumference using π = 3.14:
Substituting π = 3.14 in the circumference of the circle [tex]C=\frac{7}{2} \pi \ cm[/tex], we get;
[tex]C=\frac{7}{2}(3.14)[/tex]
[tex]C=10.99 \ cm[/tex]
Thus, the circumference of the circle is 10.99 cm
