If she has 10/12 and uses 8/12 then you just subtract.
Since the denominators are the same you just subtract 10-8 and get 2
the denominator is the same for your answers and so it is
2/12
I am assuming the angle is given in degrees.
Answer:
12.71
or in terms of Pi
182π / 45
Steps:
Formula for the arc length:
L = 2πr(θ/360)
We are given r and θ. Let’s solve for L.
L = 2* π * 8 * (92/360)
The answer is 12.71
or in terms of Pi
182π / 45
Start by multiplying six by 3 and getting 18. thendivide 23.15 by 18 = 1.2861111
that's the answer.
The area is 20
The height is 5
The volume is 60
The surface area is 94
