Answer:

301.59

96 π

Step-by-step explanation:

on khan acad. if you click on the box, you can click on the pi icon to do it in terms of pi.

I always do in terms, but make sure to learn the other way :)

the formula for cone volume is π r^2 h/3

radius = 6

height = 8

π 6^2 8/3

π 36 8/3

π 36 x 8 /3

π 288 / 3

π 96

Answer:

$h = 3\sqrt{3}$

$c = 4\sqrt{2}$

Step-by-step explanation:

✔️Finding h using trigonometric ratio:

Reference angle = 60°

Opposite = h

Adjacent = 3

Thus:

$tan(60) = \frac{h}{3}$

$\sqrt{3} = \frac{h}{3}$ (tan 60 = √3)

Multiply both sides by 3

$3\sqrt{3} = h$

$h = 3\sqrt{3}$

✔️Finding c using trigonometric ratio:

Reference angle = 45°

Hypotenuse = 8

Adjacent = c

Thus:

$cos(45) = \frac{c}{8}$

$\frac{\sqrt{2}}{2} = \frac{c}{8}$ (cos 45 = √2/2)

Multiply both sides by 8

$\frac{\sqrt{2}}{2} \times 8 = c$

$\sqrt{2} \times 4 = c$

$c = 4\sqrt{2}$

HELP ME FIND THE MEASURES OF THESE ANGLES PLEASE!!!!!!!!!!!!!!!!!!!!!

Oduvanchick [21]

1: 121, 2: 59, 3: 59

This is for the first graph because if you look at the bottom half of a circle is 180 so since one is 121 you just have to subtract 121 from 180 and you have your answer
