Step-by-step explanation:
circumference of a circle
2×pi×r
area of a circle
pi×r²
r = 8 yd
circumference is
2×3.14×8 = 3.14×16 = 50.24 yd
area is
3.14×8² = 3.14×64 = 200.96 yd²

I just guessed lol uhm yeah
Answer:
For a triangle with <em>a</em> = 33, <em>c</em> = 48 and the angle , the missing side is <em>b = </em>60.4, and the missing angles are and .
Step-by-step explanation:
The Law of Sines says that in any given triangle, the ratio of any side length to the sine of its opposite angle is the same for all three sides of the triangle. This is true for any triangle, not just right triangles.
We know two sides <em>a</em> = 33, <em>c</em> = 48 and the angle , so we use the law of sines to find the angle as follows:
One of the basic properties of triangles is that the sum of the measure of angles, in every triangle, is 180°.
So,
To find the side <em>b</em> we use the law of sines:
