Make sure you know the formula pertaining to the question.
1. c=2(pi)(r)
2. c=2(pi)(d)
r= radius
d= diameter
c= sircumference
So we are given that the circumference of a circle is 12.3pi and the radius is unknown.
So let's plug in the known values
**we use the formula with the radius, becuase we are looking for the radius.
c=2(pi)(r)
12.3(pi)=2(pi)(r)
divide each side by pi
12.3=2(r)
divide each side by 2
r=6.15 in.
Answer:
Step-by-step explanation:
each Triangle is 180° so get 180-60-30 and whatever’s left that’s your answer
Answer:
6+(-3) is 3 units from 6 in the right direction
Step-by-step explanation:
I don't know if this will be correct, but let me explain what I think, so a day has 24 hours so multiply 10 * 24 and your answer should be 240.
The diameter of a circle that has an area of 325 is 20.34
