Answer:
≈ 268 or 85.3π
Step-by-step explanation:
V = 1/3πr²h
V = 1/3 x 3.14 x 4² x 16
V ≈ 267.9467 or 268
also can be considered 85.3π
-1? I'm guessing the least
Answer:
B. 30°
Step-by-step explanation:
By remote interior angle theorem:
100° = x + 70°
100° - 70° = x
30° = x
x = 30°
Answer:
A = 1863
Step-by-step explanation:
There are a few ways you could do this but I will do the one I know best.
Keep in mind the area is the L(enght x W(idth) = A(rea)
There are two long rectangles if you cut off the square in the middle so find the area of those two first.
31 x 23 = 713
713 x 2 = 1426 (Did this to get the area for both of them.
Now find the area of the square.
23 x 19 = 437
The you would add them all up together to get 1426 + 437 = 1863
Hope this helps :)
