Perimeter of quarter circle formula =
1/4 x pi x radius + 2r
so 1/4 x 3.142 x 7
= 5.4985
5.4985 + 7 + 7
= 19.4985
≈ 19.50 ( 2 decimal place )
Answer:
y= -1/2x-8 Please see the file for better detail!
Step-by-step explanation:
To find the slope of the perpendicular line you have to find the opposite reciprocal, which means flip the number and give a negative because the original slope is positive. Please see the image for better detail. Use point slope, slope intercept forms to find your answer.
Solve using the addition property of equality. Be sure to check your proposed solution.

The next higher million is 68 million.
The next lower million is 67 million.
67,492,384 is closer to 67 million than to 68 million.
So the nearest million is 67,000,000 .
You would need to find the circumstance which the formula is pi*D. with D being the diameter. you would multiply 14 by 3.14 and get 43.96. Therefore the circumstance would be 43.96. hope this helped
