Equation for circumference is c = 2(pi)r
r = 1/2(d)
d = 20
So…. r = 1/2(20) = 20/2 = 10
Going back to circumference equation
c = 2(pi)(10) = 2(3.14)(10) = 62.8
You have to give every thing that the problem says for me to be able to figure it out.
Answer:
B. 1/2
Step-by-step explanation:
Make 9 an improper fraction, then multiply by -5/6.
-5/6 times 9/1 = -45/6.
-45/6 cannot be simplified, so you make it a mixed number.
-7 1/2.
Add the 7 to -7 1/2 and that cancels out to 1/2
Answer:
both are at the same distance
