Answer:
1900.66
I don't see the answer there in the list of options, maybe I got the values wrong...
Step-by-step explanation:
This pic is blurry so I'm going to assume the numbers given are 3, 8, and 11.
Volume of larger cylinder:
π*r^2*h
(π)(64)(11) = 704π
Volume of smaller cylinder:
π*r^2*h
(π)(9)(11) = 99π
Subtract the two answers together:
704π - 99π = 605π
Simplify:
605π ≈ 1900.66
Answer:
Step-by-step explanation:
The formula for the length of an arc is s = rФ.
Thus, the arc length of a semicircle is S = rФ/2.
Here the radius is 5 (half the diameter), and so in this case the arc length is
S = (5 units)π/2, or S = (5/2)(3.14) units, or approximately S = 7.85 units
Answer:
41
Step-by-step explanation: 180 is the full amount of angles in a triangle
101+38 is 139
180-139 is 41
Answer:
-30
Step-by-step explanation:
f(x) = 3 so f(-8) = 3;
g(x) = 5x + 7, so g(-8) = 5(-8) + 7 = -33
Then (f + g)(-8) = 3 - 33 = -30
This is the sum of two functions both evaluated at x = -8.
