Answer: 1/3=3(n)+12
Step-by-step explanation:
Answer: Ok So If you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π. π is roughly equal to 3.14.
The formula for working out the circumference of a circle is:
Circumference of circle = π x Diameter of circle
This is typically written as C = πd. This tells us that the circumference of the circle is three “and a bit” times as long as the diameter."

Answer:
Length of arc AB = 1.57 yds
Step-by-step explanation:
Given:
Central angle (θ) = 30°
Radius (r) = 3 yds
Required:
Length of arc AB approximated to the nearest hundredths
Solution:
Length of arc = θ/360 * 2πr
Length of arc AB = 30/360*2*π*3
Length of arc AB = 1.57079633
Length of arc AB = 1.57 yds (nearest hundredths)
Answer:
supplementary and straight
Step-by-step explanation:
1. angle D and angle B add up to make a 180 degree angle so they are supplementary.
2. A and C each equal 180 degrees (straight angle= 180 degrees)
