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

The regular nonagon has rotational symmetry of which angle measures? Check all that apply.

11111nata11111 [884]

Consider the center of the nonagon. If we join the center to all the vertices, the central angle of 360°, is divided into 9 equal angles, each with a measure of:

360°/9=40°

So to a nonagon rotated 40°, clockwise or counterclockwise, is indistinguishable from the original one.

similarly if we rotate 80 ° c.wise or c.c.wise

in general, a nonagon has a rotational symmetry of 40°n,

where n∈{...-3, -2, -1, 0, 1, 2, 3}...

where 40°n, for n negative, means we are rotating clockwise.

Answer: any angle which is a multiple of 40°
