Smaller circle:
diameter = 9 ft
radius = diameter/2 = (9 ft)/2 = 4.5 ft
A = pi(r^2) = 3.14159 * (4.5 ft)^2 = 63.62 ft^2
Larger circle:
diameter = 20 ft
radius = diameter/2 = (20 ft)/2 = 10 ft
A = pi(r^2) = 3.14159 * (10 ft)^2 = 314.159 ft^2
Difference = larger are - smaller area
Difference = 314.16 ft^2 - 63.62 ft^2 = 250.54 ft^2
Answer: About 251 ft^2
Answer:
4x²
Step-by-step explanation:
Your equation is 4x² - 6x² + 7x² - 20x² + 19x².
Since they all have the same variable, simply combine them all to find your answer.
4x² - 6x² + 7x² - 20x² + 19x²
-2x² + 7x² - 20x² + 19x²
5x² - 20x² + 19x²
-15x² + 19x²
4x²
Pretty sure it’s irrational
Answer:
R = -2
Step-by-step explanation
-9, -3 is the first point.
A slope of 1/7 means that for every one unit that "rises" it will have a "run" of 7 units.
-9 - 7 = -2
-3 - 1 = -2 (r)
with a slope of 1/7, (-9, -3) connects to (-2, -2)
Pls mark me brainliest if right thank you
Theoretically, you should be able to travel 396 miles on a full tank of gas. I found this by multiplying 22 and 18 because you can get 22 miles for every single gallon, and you have 18 gallons.
