In Circle O, centrally angle AOB measures π/3 radians.What is the length of arc AB?
Oksanka [162]

Answer:

s=r*\pi /3

Step-by-step explanation:

The length of any arc is calculated using the following equation:

s = r*θ

Where s is the length of the arc, r is the radius of the circle and θ is the angle in radians.

So, if we have a Circle O and a centrally angle AOB that measures π/3 radians, the value of the length of arc AB is calculated as:

s=r*\pi /3

Where r is the radius of the circle O.

Athena is trying to drink more water, so she has been keeping a log of how much water she drinks. Two days ago, Athena drank 80

Hello There!

Percentage increase or decrease = difference of values / original value.  x 100
Percentage decrease = 80 - 76/80
80 - 76 = 4
4/80 = 0.05
0.05 x 100 = 5

In short, the decrease in Athena's daily water consumption is 5%.

Hope This Helps You!
Good Luck :)
