Answer:
125.66
Step-by-step explanation:
11cm squared times pi =380.13
9cm squared times pi =254.47
380.13-254.47=125.66
Answer:
Part 1) The exact value of the arc length is 
Part 2) The approximate value of the arc length is 
Step-by-step explanation:
step 1
Find the circumference of the circle
The circumference of a circle is equal to

we have

substitute


step 2
Find the exact value of the arc length by a central angle of 150 degrees
Remember that the circumference of a circle subtends a central angle of 360 degrees
by proportion

step 3
Find the approximate value of the arc length
To find the approximate value, assume

substitute

Given parameters:
First point = (12, -5)
Second point = (10, -4)
Unknown:
Slope of the line = ?
Slope is simply the vertical rise divided by the horizontal distance.
Slope = 
Simply to find slope;
Slope = 
First point = (12, -5), x₁ = 12 and y₁ = -5
Second point = (10, -4), x₂ = 10 and y₂ = -4
Input the parameters:
Slope = 
= 
= - 
The slope of the line is -
Answer:
Step-by-step explanation:
Line 1 is parallel and slope -1.33333 or -4/3
Line 2 is parallel and slope 0.75 or 6/8
Line 3 is parallel and slope 0.75 or -3/-4 i got the answers on Omni calculator
