Answer:
d = 6 units
Explanation:
Circumference of the circle is given by:
where, d is the diameter of the circle.
As per the statement:
Given a circle 1 with measures of (C, d, and r) and a circle 2 with measures of (C', d', and r').
Circumference of a circle(C) 1 with diameter(d) is given by:
.....[1]
Also, the circumference of a circle (C') 2 with diameter(d') is given as:
Divide equation [1] and [2] we have;
⇒
Substitute the given values
and d' = 0.50 then;
Multiply both sides by 0.50 we have;
6 = d
or
d = 6 units
Therefore, the value of d is, 6 units
