Step-by-step explanation:
Answer:
π/4
Step-by-step explanation:
The reference angle will be the minimum of the absolute value of the angle, and the difference of that absolute value and pi.
ref angle = min(|-3π/4|, π -|-3π/4|) = min(3π/4, π/4)
ref angle = π/4

Answer:263.89cm cubed
Step-by-step explanation:
Volume of A Sphere: 4/3 pi radius cubed
4cubed= 64
64 times pi=201.061
201.061 multiply 4/3= 268.08
1cubed= 1
1 times pi=3.14
3.14 times 4/3= 4.19
268.08-4.19= 263.89cm cubed
Answer:
y = 2 x = -7
Step-by-step explanation:
2x+5y=-4 2x + 5y = -4 Add both equations
(-x-3y=1)2 -2x - 6y = 2
-y = -2
y = 2
Plug in 2 for y in the equations
-x - 3(2) = 1
-x -6 = 1
-x = 7
x = -7
