arc length (s) = radius (r) · angle (θ) (the angle must be in radians!)
45° = 
s = 8 ·
= 
= 2π
Answer: 2π
The correct answer is 13m+(2.7x8)
If the line is perpendicular, that means the slope has to be opposite, so it will have a slope of -1/2
Fill in the point that it has to pass through on y and x
1=-1/2(0) + b
1=0+b
1=b
Then go back to the standard form y=mx + b and fill in the slope and y intercept
Y= -1/2x + 1
Answer:
Area= 64pi or 201.06
Circumference: 16pi or 50.265
Step-by-step explanation:
Area= \pi r^{2}
pi (8)^2 = 64pi or 201.06
Circumference= 2pir , 2(pi)8 = 16pi or 50.2
