Answer:
r =2.9985yd
Step-by-step explanation:
Given that the circumference of a circle is 2
r
where r is the radius and
= 3.1415926....
You have
2
r = 18.84 yd
2(3.1415926)r = 18.84 yd
6.2831r = 18.84yd
divide through by 6.2831
r = 2.9985yd = aprox 3yds
when you add two negatives its just like regular number, -3+-5=-8 same as 3+5=8
Answer:
Measure of arc ZWX is <u>230°.</u>
Step-by-step explanation:
Given:
arc WX = 50°
Now
The diameter divide a circle into two equal parts
so

Since WZ is diameter of the circle.
substituting in above equation we get

Hence Measure of arc ZWX is <u>230°.</u>
