Answer:

y = 22.5

Step-by-step explanation:

Here, the 4 angles shown are all exterior angles of the polygon.

The sum of the exterior angles of a polygon is ALWAYS 360°

<em>So we add up the 4 angles (given in terms of y) and sum it to 360 and solve for y:</em>

$4y+2y+6y+4y=360\\16y=360\\y=\frac{360}{16}=22.5$

y = 22.5

Rearrange the equation A = xy to solve for x.

mote1985 [20]

X = A/y
You divide the y from both sides
The y on the right cancels
On the left you have A/y = x

What is the volume of the cone? cone v = one-third b h startfraction 70 over 3 endfraction pi centimeters cubed startfraction 14

Bas_tet [7]

Using the assumed values, the volume of the cone is $V = \frac {250}3\pi$

<h3>How to determine the volume of the cone?</h3>

The volume of a cone is calculated using:

$V = \frac 13\pi r^2h$

The parameters are not given.

So, we use the following assumed values

Radius, r = 5

Height, h =10

Using the assumed values, we have:

$V = \frac 13\pi * 5^2 * 10$

Evaluate the product

$V = \frac {250}3\pi$

Hence, using the assumed values, the volume of the cone is $V = \frac {250}3\pi$
