Answer:
3925 units²
Step-by-step explanation:
area of larger circle = πr² = (3.14)(250²) = 196,250
area of smaller circle = πr² = (3.14)(200²) = 125,600
area of full donut = 196,250 - 125,600 = 70,650
20/360 = 1/18 of full donut
1/18(70,650) = 3925 units²
Answer: B, D, and E
<u>Step-by-step explanation:</u>
f(x) = x² - 1
(0, 1): 1 = (0)² - 1 ⇒ 1 = -1 FALSE
(1, 0): 0 = (1)² - 1 ⇒ 0 = 0 TRUE
(3, 5): 5 = (3)² - 1 ⇒ 5 = 8 FALSE
(5, 24): 24 = (5)² - 1 ⇒ 24 = 24 TRUE
(-2, 3): 3 = (-2)² - 1 ⇒ 3 = 3 TRUE
(-4, -17): -17 = (-4)² - 1 ⇒ -17 = 15 FALSE
Answer:
x=12

Answer:
oh hey I gotchu-
first of all you are gonna make that into two rectangle by slicing the top off if that makes sense so you now have a large rectangle (11×12) and a small one (3×8) now you use the area formula for rectangles base×height so the small one becomes (3×8)=24 and the large one is (11×12)=132. now to make them into one shape for the total area you add those two values 132+24=156 so your total area is 156m²
