Use the Unit Circle to find the exact value of the inverse trig function.

Vedmedyk [2.9K]

Answer:

330

Step-by-step explanation:

When we are at 30 degrees on the unit circle, we are at the point ( $\sqrt3$ /2, 1/2) so if we go to -30 degrees (330 degrees), we will be at point (- $\sqrt3$ /2, -1/2).

A right circular solid cone of base radius 42cm and height 84cm has the same volume as a solid cylinder of height 112cm find the

11Alexandr11 [23.1K]

Answer:

21 cm

Step-by-step explanation:

Volume of cone is given by $1/3(\pi r^2h)$

volume of cylinder is given by $\pi r^2h$

where r is the radius of base and h is the height

_________________________________

For cone

radius = 42cm

height = 84

volume = $1/3(\pi *42^2*84)$ (1)

________________________________

For cone

radius = to find let it be r

height =112

volume = $\pi *r^2*112$ (2)

_______________________________________

since , volume of both solid are same

thus, equation 1 = equation 2

$1/3(\pi *42^2*84) = \pi *r^2*112\\=> r^2 = 1/3((\pi *42^2*84) / 112*\pi \\=> r^2 = 1/3(42*42*84/112) = 441\\=> r = \sqrt{441} \\=> r = 21$

Thus, radius of cylinder is 21 cm

What is the value of s???

tangare [24]

Answer:

Step-by-step explanation:

2s+9=21

2s=12

s=6.

If both sides are equal like that I would assume that the triangle was equilateral, meaning that you would set the entire side up to 21 and solve from there
