6/15=2/c Please show me how to solve

seropon [69]

6/15 = 2/c...this is a proportion, so we must cross multiply
(6)(c) = (15)(2)
6c = 30..divide both sides by 6
c = 30/6
c = 5

and if u will notice...6/15 = 2/5...proportions are nothing but equivalent fractions.

Please find the area and circumference of the circle with diameter 3.7cm

steposvetlana [31]

Answer:

Area: 10.7521 cm

Circumference: 11.62389 cm

________________________________________________________

<h3>Solve: Area</h3>

Area, <em>A,</em> will equal the formula of $\pi r^2$ , so we must find the value and split that up. Diameter, <em>d</em> is equal to 2<em>r</em>. Let's solve.

$A = \pi r^2$

$d = 2r$

Now, make an equation combining like terms.

$A = \frac{1}{4} \pi d^2$

This equation means to multiply those terms together. Since the diameter is 3.7, <em>d</em> is 3.7

$\frac{1}{4} * \pi * 3.7 = 10.8(estimate)~cm$

<em>Let's move on to circumference. On we go!</em>

________________________________________________________

<h3>Solve: Circumference</h3>

With circumference, it is very similar to what you just did to find area(<em>A</em>). You must again, set up these terms and make an equation out of them. C(circumference) is going to be equal to $\pi r$ , notice how it does not say <em>squared</em>( $^2$ ) at the end now.
