The diameter of a circle is 10 kilometers. What is the circle's radius?<br> d=10 km
alexandr402 [8]

Step-by-step explanation:

Let diameter of the circle be d and radius be r.

\therefore \: r =  \frac{d}{2}  \\  \\   \therefore \: r =  \frac{10}{2}  \\  \\ \therefore \: r = 5 \: kilometers.

Hence radius of the circle is 5 kilometers.

If cote = and the terminal point determined by a is in quadrant 3, then:
erma4kov [3.2K]

Answer:

The correct option is:

cosθ = -3/5

Step-by-step explanation:

We have been given that:

cotθ = 3/4

such that the terminal side of θ lies in III quadrant.

Consider it a right angled triangle.

We know that:

cotθ = Base / Perpendicular

Which means Base has a magnitude of 3 and Perpendicular has the magnitude of 4.

As It lies in III quadrant, both x and y are negative.

So

Base = -3

Perpendicular = -4

Find the hypotenuse by using Pythagoras Theorem

H² = (-3)² + (-4)²

H = 5

We know that:

cosθ = Base / Hypotenuse

cosθ = -3/5
