Area of circle is 314 inches^2
Circumference of circle is 62.8 inches
Step-by-step explanation:
We need to find area and circumference of the circle whose diameter is 20 inches.
Area of circle
The formula used to find area of circle is:
value of π = 3.14
we know radius = diameter/2
So, radius = 20/2 = 2
Putting value of π and radius we get Area:
So, Area of circle is 314 inches^2
Circumference of Circle
The formula used to find circumference of circle is:
value of π = 3.14
diameter= 20
Putting value of π and diameter we get Circumference:
So, circumference of circle is 62.8 inches

Answer:
D
Step-by-step explanation:
Let's draw a picture (see attachment).
We know that since our point is (-5, -12), it must pass in the third quadrant. Now, if we drop a perpendicular line from the point (-5, -12) to the x-axis, we have a right triangle. Notice that we already know the two leg lengths of this: -5 and -12.
Cosine is adjacent / hypotenuse. Here, the adjacent side to the angle θ is -5. We need to find the hypotenuse, which we can do so by using the Pythagorean Theorem:
c² = a² + b²
c² = (-5)² + (-12)²
c² = 25 + 144 = 169
c = 13
So, the hypotenuse is 13. Now, plug these values in:
cos(θ) = adjacent / hypotenuse = -5/13
The answer is D.
