Find the primary solution of cosθ=−0.3 ⁡

Mathematics
1 answer:
Agata [3.3K]3 years ago
4 0

The solution of cos θ = −0.3 is θ = 107.45760312 degrees

<em><u>Solution:</u></em>

Given that we have to find the primary solution of cos \theta = -0.3

To solve this equation, you must find the unknown (theta)

cos \theta = -0.3

Use the inverse of cosine (Arccos) to find the angle measurement (in degrees) of theta

\theta = arccos (-0.3)

We know that arccos (-0.3) = 107.45760312 degrees

[ If you reference a unit circle or use a calculator ]

\theta = 107.45760312^{\circ}

Therefore solution of cos θ = −0.3 is θ = 107.45760312 degrees

The volume of a cylinder is the area of the circular face times the length of the cylinder.

the area of a circular face is
 A=\pi r^2 = \pi\frac{d^2}{4}

hence the volume is
V= \pi r^2 L = \pi \frac{d^2}{4} L

the Length "L" is 36 in
the diameter "d" is 3 in
