a) So we know the formula of finding the circumference: 2*pi*R.
Assuming we make pi = 3.14: 2 * 3.14 * 7 = 43.96.
b) We also know the formula of finding the area: pi * r^2.
3.14 * 7^2. Using PEMDAS:
3.14 * 49 = 153.86
Answer:
x=841/68
Step-by-step explanation:
-68(x-11)=1+(-94)
-68(x-11)=-93
-68x+748=-93
-68x=-93-748
-68x=-841
68x=841
x=841/68
I am sorry but this is incomplete. If you would like to PM me the full question I would love to help?
