Find the measure of arc BC

Mathematics

lesantik [10]3 years ago

Answer:

Step-by-step explanation:

This problem does not specify what the radius of the circle is, and so we will have to represent that by r.

Arc length = s = rФ, where Ф is the central angle in radians.

Converting 162° into radians:  

162°        1 rad

------- · ------------ = 0.9 rad

    1        180°

Then the arc length BC is s = rФ, or r(0.9 rad)

If, for example, r = 10 m, then the arc length would be (10)(0.9) m = 9 m

This is adding two vectors, one magnitude 300 direction east, and one magnitude 100 direction 30 degrees northeast.

For the resulting sum we can use the Law of Cosines or just add up the components.  Let's try it both ways.

Components first.   In the east direction we have

300 + 100 cos 30° = 300 + 100(√3/2) = 386.60 miles per hour

In the north direction we have

0 + 100 sin 30° = 100 (1/2) =  50 miles per hour

So a total speed of

sqrt{386.6^2 + 50^2} = 389.82 miles per hour

Answer: 389.82

--------

OK let's try the Law of Cosines.   We have sides 300 and 100 and included angle 150°.

c^2 = 300^2 + 100^2 - 2 (300)(100) \cos 150^\circ

c=\sqrt{151961.52422} = 389.82 \quad\checkmark

A cone has a base area of 8 cm^2 and a height of 3.8 cm. What is the volume of the cone?
Nitella [24]
The answer is:  30.4 cm³ .
________________________________________________________

The volume = Base Area * height = (8 cm²) * (3.8 cm) = 30.4 cm³ .
