Answer:
D
Step-by-step explanation:
givens
r = 1.9 m
h = 11 m
Equation
V = pi * r^2 * h
Solution
V = pi * 1.9^2 * 11
V = pi * 3.61 * 11
V = pi * 39.71
V = 39.71 pi
Answer:803.84
Step-by-step explanation:
3.14 x (16^2) = 803.84.
16^2 is 256 so multiply that by 3.14
Answer:
In the explanation
Step-by-step explanation:
a) Multiply the second equation by 2, subtract both lines. You get x = -3. Plug this in to get y, y = -2
b) Multiply the first equation by 2, add both lines. You get x = 8. Plug this in to get y, y = -3
c) Multiply the first equation by 5, subtract both lines. You get y = 1. Plug this in to get x, x = -3
d) Multiply the first equation by 2 and the second one by 3, add both lines. You get x = 1. Plug this in to get y, y = 4
Hope this helps!
Answer:
V = a³/8
Step-by-step explanation:
The volume of the original cube is the cube of the side length:
V = a³
When the side length is reduced to half its former value, the new volume is ...
V = (a/2)³ = a³/2³
V = a³/8 . . . . volume of the new cube
