Answer:
The answer is (π/4)*r
Step-by-step explanation:
Formula length of arc when the angle given is in radian as the case given
s = r*θ
s = arc length (in radians)
r = radius
θ = central angle in radians
But when the angle given is in degrees the length is expressed as
s= 2πr*(θ/360)
I took the test. Here's the right answer
Answer:
54 - 10y
Step-by-step explanation:
Distribute each of the 3 parenthesis
= 12y + 24 - 32y + 32 - 10y - 2 ← collect like terms
= 54 - 10y
Average = Mean
To find the mean, add up the numbers and divide it by how many numbers there are.
So,

There are 5 numbers in total.

To do these types of division, ignore the decimal and add a 0 at the end.
So we can do:

And put back the decimal.
Hope this helps :)
