Question

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?

Answer 1

Answer:

I think the D equals one (1) based on the info i was given

Step-by-step explanation:

Answer 2

Answer:

d = 6 units

Step-by-step explanation:

Circumference of the circle is given by:

$C = \pi d$

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:

$C = \pi d$               .....[1]

Also, the circumference of a circle (C') 2 with diameter(d') is given as:

$C' = \pi d'$

Divide equation [1] and [2] we have;

$\frac{C}{C'} = \frac{\pi d}{\pi d'}$

⇒$\frac{C}{C'} = \frac{d}{d'}$

Substitute the given values $\frac{C}{C'}=12$ and d' = 0.50 then;

$12 = \frac{d}{0.50}$

Multiply both sides by 0.50 we have;

6 = d

or

d = 6 units

Therefore, the value of d is, 6 units
