We need to evaluate the value of fraction \frac{j}{4}.

We also given j=12.

In order to evaluate the value of fraction \frac{j}{4}, we need to plug j=12.

Plugging j=12, we get

\frac{j}{4}= \frac{12}{4}

We have 12 in numerator and 4 in denominator.

We always divide top number by bottom number.

So, we need to divide 12 by 4.

On dividing 12 by 4 we get 3.

<h3>Therefore, \frac{j}{4} = 3.</h3>

**BRAINLIEST IF ANSWERED***
goblinko [34]

Answer:

(D)7 in.

Step-by-step explanation:

A regular hexagon can be divided into six equilateral triangles.

Therefore:

b=\dfrac{c}{2}

Applying Pythagoras Theorem

c^2=12^2+b^2\\c^2=12^2+(\frac{c}{2})^2\\c^2-(\frac{c}{2})^2=12^2\\c^2-\dfrac{c^2}{4}=144\\\dfrac{4c^2-c^2}{4}=144\\\dfrac{3c^2}{4}=144\\$Cross multiply\\3c^2=144 \times 4\\3c^2=576\\$Divide both sides by 3\\c^2=192\\$Therefore:\\c=\sqrt{192}\\c=8\sqrt{3}$ in.

Recall that b=c/2

Therefore:

b=4\sqrt{3} \approx 7$ in.

The value of b is 7 inches.

I’m gonna ask this question again can someone help me solve this and leave in terms of pi
scoundrel [369]

The equation of the circumference of a circle in terms of \pi is 2\pi r or \pi d.

The circumference for a circle with diameter 10 is 10\pi.

The circumference for a circle with diameter 19 is 19\pi.

The circumference for a circle with diameter 30 is 30\pi.

The circumference for a circle with diameter 16 is 16\pi.

Relatively easy, right?

The equation of the area of a circle in terms of \pi is \pi r^2.

The area of a circle with radius 5 is 25\pi.

The area of a circle with radius 9.5 is 90.25\pi.

The area of a circle with radius 15 is 225\pi.

The area of a circle with radius 8 is 64\pi.

Hope this helped!

(By the way, I don't know why you're using hard formulas for trying to find the radius or diameter. The diameter is simply twice the radius, and the radius is simply half the diameter.)
