Given a circle with measures of (c, d, and r) and a circle with measures of (c', d', and r'), what is d if c c' = 12 and d' = 0.50?

d = 6 units

Step-by-step 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

answer: your correct answer is b. d.
