Finally, you make an approximately circular yard using 80 ft of fence. What is the area of the yard? (Hint: First find the radiu

Pavel [41]

Since the circumference is 80, you know that the equation used was:
$\pi d = 80$
Divide by pi and you'd get d = 25.465
Divide that by 2 to get your radius.
25.465 / 2 = 12.723 = r

The area formula for a circle is $\pi r^2$
So, $\pi (12.723)^2$ = 508.544 square feet

Help please, i don't understand it!!!!

velikii [3]

$V=\dfrac{4}{3}\pi r^3\ \ \ |\cdot\dfrac{3}{4}\\\\\pi r^3=\dfrac{3V}{4}\ \ \ \ |:\pi\\\\r^3=\dfrac{3V}{4\pi}\ \ \ |:r\\\\r^2=\dfrac{3V}{4\pi r^2}$

Substitute to S.A.

$S.A.=4\pi r^2=4\pi\cdot\dfrac{3V}{4\pi r^2}=\dfrac{3V}{r}$

$\dfrac{S.A.}{V}=\dfrac{4\pi r^2}{\frac{4}{3}\pi r^3}=\dfrac{3}{r}$

$\dfrac{S.A.}{V}=1\to\dfrac{3}{r}=1\to r=3$

How are the two angles below related? A) Drawing not to scale. B) complementary .C) supplementary. D) adjacent. E) vertical

mamaluj [8]

Answer:

Option C) supplementary

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

If two angles are supplementary, then their sum is equal to 180 degrees

In this problem

The measure of angles are

60° and 120°

Their sum is equal to

60° + 120°=180°

therefore

The two angles are supplementary
