Answer :
exact formula of circumference in diameter in 3.14*d=3.14d
and in terms of radius= 3.14*2r=6.28r
and in terms of radius= 3.14*2r=6.28r
Answer:
Circumference of a circle is given by:
[tex]C = 2\pi r[/tex]
where
C represents the circumference of a circle.
r represents the radius of a circle.
As per the statement:
Use [tex]\pi = 3.14[/tex] and diameter(d) = 2r units
Circumference in terms of diameter (d) is:
[tex]C = 2 \pi r = \pi (2r) = \pi d[/tex]
Substitute the value of [tex]\pi = 3.14[/tex] we have;
[tex]C = 3.14d[/tex] units
Now:
find the circumference in terms of radius r.
[tex]C = 2 \pi r[/tex]
[tex]C = 2 \cdot 3.14 \cdot r = 6.28r[/tex] units
Therefore, the exact formula for the circumference in terms of the diameter, d is, C = 3.14d and in terms of r is C= 6.28r.
