Answer:
c = 2 * 3.14 * r and c = 3.14 * d
Step-by-step explanation:
The formulas for the circumference of a circle are
c = 2πr and c = πd
where r is the radius and d is the diameter
using π = 3.14
the formulas become
c = 2 * 3.14 * r and c = 3.14 * d

Answer:
Step-by-step explanation:
125/x=100/0.35
(125/x)*x=(100/0.35)*x - we multiply both sides of the equation by x
125=285.71428571429*x - we divide both sides of the equation by (285.71428571429) to get x
125/285.71428571429=x
0.4375=x
x=0.4375
now we have:
0.35% of 125=0.4375
Step-by-step explanation:
