Answer:
13.7 cm
Step-by-step explanation:
- there are 360° in a circle and in this image, we can see 90°+90°+66.4°=260.4
- since we know that 360°-260.4°=99.6°
- The angle measure of arc AD is 99.6°
Now that we covered that, we can use the arc length formula in order to find the length of arc AD.
- arc length = 2πr(Θ/360°)
- 2π(7.9)(99.6°/360°) = 13.7329
- rounded to the nearest tenth = 13.7
There is 20% decrease in the number of members.
Step-by-step explanation:
Given,
Members last year = Old value = 30
Members this year = New year = 24
Change = New value - Old value
Change = 24 - 30
Change = -6
The negative sign indicates the decrease.
Decrease percent = 
Decrease percent = 
Decrease percent = 
Decrease percent = 20%
There is 20% decrease in the number of members.
