Is one half equal to 7/12

yuradex [85]

We can chang efractions to compare them by multiplying them by 1 or x/x where x=x so

1/2=7/12?
make bottom numbers equal
2 times what=12
divide 2
what=6

1/2 times 6/6=6/12
6/12=7/12
6=7
false

so therefor it does NOT equal 7/12

If the circumference of a circle measures 12π cm, what is the area of the circle in terms of π?

frez [133]

So the formula for the circumference of a circle is π x diameter
Since we know the the circumference already, we just divide that by π:

12π / π = 12

Now we halve the diameter to get the radius:
12 / 2 = 6

The area of a circle is π x radius²
So the area is:

·π x 6² = 36π· (or 113 not in terms of π)

The formula for finding the volume of a nose cone of an aircraft is V = (pi * d ^ 2 * h)/6 where d is the diameter of the base o

adell [148]

Answer:

$h=\frac{6V}{\pi d^2}$

Step-by-step explanation:

we have

$V=\frac{\pi d^2h}{6}$

Solve for h

That means ----> isolate the variable h

step 1

Multiply by 6 both sides

$6V=\pi d^2h$

step 2

Divide by $\pi d^2$ both sides

$h=\frac{6V}{\pi d^2}$
