Answer:
The approximate length of the radius, r is 12 inch.
Step-by-step explanation:
Given:
A circle P is given having circumference C,
C = 75 inch
pi = π = 3.14
radius = r
To Find:
radius = r = ?
Solution:
Circumference:
In geometry, the circumference (from Latin circumferens, meaning "carrying around") of a circle is the (linear) distance around it.
That is, the circumference would be the length of the circle if it were opened up and straightened out to a line segment.
Formula is given as
[tex]Circumference=2\pi (radius)[/tex]
Substituting the values we get
75 = 2 × 3.14 × r
∴ [tex]r =\frac{75}{2\times 3.14}\\ \\r=\frac{75}{6.28} \\\\r=11.942\ inches[/tex]
We approximate radius to
radius = 12 inich
