You have to plug the known x value into the problem. You know that x is the same thing as saying 5, so you can say that 6x is the same thing as 6(5) which equals 30, now that the x value is know there will not be any x’s in the solution. So the solution is just 30.

Answer:

(b)

$V_2 = \frac{\pi}{4} [ \frac{(2r)^2h}{3}]$ or $V_2 = \frac{1}{3}\pi r^2h$

Step-by-step explanation:

Given

$Ratio = \frac{\pi}{4}$

See attachment for complete question

Required

Determine the volume of the cone

The volume of a square pyramid is:

$V = \frac{a^2h}{3}$

Where

a = base dimension

From the attachment, the base dimension of the square pyramid is 2r.

So:

$a = 2r$

The volume becomes;

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

To calculate the volume of the cone, we simply multiply the given ratio and the volume of the prism.

So, we have:

$V_2 = Ratio * V$

$V_2 = \frac{\pi}{4} [ \frac{(2r)^2h}{3}]$

$V_2 = \frac{\pi}{4} * \frac{(2r)^2h}{3}$

Open bracket;

$V_2 = \frac{\pi}{4} * \frac{4r^2h}{3}$

Cancel out 4

$V_2 = \pi * \frac{r^2h}{3}$

The above can be written as:

$V_2 = \frac{1}{3} * \pi r^2h$

$V_2 = \frac{1}{3}\pi r^2h$

So, we have:

$V_2 = \frac{\pi}{4} [ \frac{(2r)^2h}{3}]$

or

$V_2 = \frac{1}{3}\pi r^2h$

Find the area of the geometric figure.<br> 3 yd<br> 3 yd<br> Traperoid<br> 7 yd

Reika [66]

Step-by-step explanation:

The question isn't clear, so I'll just give you a formula to find the area of trapezoid,

(a+b)*h/2, where a = base side, b = top side, h = height.

So, let's say two sides are 3 yd and 7 yd, and height is 3 yd, so the area becomes,

(3+7)*3/2

= 10*3/2

= 30/2

= 15 yd²
