What is the length of arc S shown below?

1 answer:

5 0

An angle in radians marks out the same number of radiuses on the circle. That's one thing that often makes radians so neat to work with.

The angle in the middle of this circle is 2 radians. So the arc ' S ' is 2 times the length of the circle's radius.

In my head, I get S = 14 units , but you should check it out.

Answer:

Step-by-step explanation:

For missing hypotenuse: $\sqrt({a^{2} + b^{2})$

Plug in the side lengths that are known to find the hypotenuse.

1. No, the angle is less than 18 degrees (closer to 15), so it is not safe

2. The length rounded to the nearest tenth is approximately 15.5 feet.

What is the exact distance from (−1, 4) to (6, −2)?

Studentka2010 [4]

Same as last time:

d^2=(x2-x1)^2+(y2-y1)^2

d^2=(6--1)^2+(-2-4)^2

d^2=7^2+(-6)^2

d^2=49+36

d^2=85

d=√85 (85=5*7 and both 5 and 7 are prime so √85 cannot be simplified any further)

The exact distance is √85 units.
