Answer 11

Like 4 Real

Answer 12

Arcs are measured in three different ways. They are measured in degrees and in unit length as follows:

Degree measure of a semicircle: This is 180°. Its unit length is half of the circumference of the circle.
Degree measure of a minor arc: Defined as the same as the measure of its corresponding central angle. Its unit length is a portion of the circumference. Its length is always less than half of the circumference.
Degree measure of a major arc: This is 360° minus the degree measure of the minor arc that has the same endpoints as the major arc. Its unit length is a portion of the circumference and is always more than half of the circumference.

@precal

Answer 26

ok one sec lemme figure this one out

Answer 28

Sorry I couldnt help @gswag98

Answer 29

19.28588823

Answer 30

Arc length is radius times theta
its a formula we use in precalculus

Answer 31

let me know if that is correct, just typing it off the top of my head

Answer 32

it's wrong and now there's a new question

Answer 33

on my program

Answer 52

120

Answer 53

120 degrees is the minor arc
240 is the major arc
sorry we were doing arc length

Answer 54

all questions came from program today and on these questions right now are from the practice test

Answer 55

no we were doing area of a sector, just remember that is area of a sector

Answer 56

did 120 work

Answer 57

no 120 didn't work now this is my last chance to answer the question

Answer 58

I need the answer before my program kicks me off and I gotta start all over again

Answer 61

seriously

Answer 62

Answer 63

ok let me figure this out I got the formula

Answer 64

2 times pi times radius times (degrees over 360)
wait let me do this in a moment

Answer 65

sorry I am still getting the same answer 16.76 so I can't help you

Answer 66

\[2\pi(8)\frac{ 120 }{ 360 }\]

Answer 67

HEEEEEELLLLLLLPPPPP!!!!!!

Answer 68

gahhh

Answer 69

Nevermind I got 80 percent on the practice test

Answer 70

We already saw this question yesterday.
The answer (using an approximation of pi from a calculator) is 16.76 rounded to 2 decimal places.
If pi is rounded to 3.14, then the answer would be 16.75.
