Well logically thinking 16 could not be less than 3!, That is not a reliable answer but more of an opinion!

Need to find the volume. measurements in picture, please help.

o-na [289]

Answer:

V = 288.5 $yd^{3}$

Step-by-step explanation:

To find the volume of a cone, use this equation:

$V = \pi r^{2}\frac{h}{3}$

r = radius

h = height

We aren't given the height of the cone, just the length of the side. To find the height use the Pythagorean Theorem:

$a^{2}+ b^{2}= c^{2}$

The value of 12.1 yds is the hypotenuse and the radius is the value of one of the legs. So, set it up like this:

$a^{2}+5^{2} =12.1^{2}$

Now, solve:

$a^{2}+25= 146.41$ Distribute the square

$a^{2} = 121.41$ Subtract 25 from 146.41

$\sqrt{a^{2} }=\sqrt{121.41}$

a = 11.01862

So, the height is equal to 11.01862 yds.

Now, we can plug everything into the volume equation:

$V = \pi (5)^{2}\frac{11.01862}{3}$

Simplify (use calculator):

V = 288.5 $yd^{3}$

So, the volume of the cone is equal to 288.5 $yd^{3}$

What formula can we use to find the surface area of a rectangular prism?

saveliy_v [14]

Answer:

○ $\displaystyle SA = 2lw + 2lh + 2wh$

Explanation:

A rectangle has four right angles, including two pairs of congruent edges, only containing two dimensions – height and length. Therefore, going three-dimensional, a rectangular prism has three dimensions – width, height, length. With this information, you should know what the answer is.

I am joyous to assist you at any time.

−2(x + 3) = −2(x + 1) − 4.

IrinaVladis [17]

$- 2(x + 3) = - 2(x + 1) - 4 \\ - 2x - 6 = - 2x - 2 - 4 \\ - 2x = - 2x \\ x = x$

Every x is a solution.
