Answer:
75 ft
Step-by-step explanation:
Area = 300 Sq ft
Height = 4ft
Length =?
Area =L xH
300 /4 =L
Length =75ft
Answer:
12
Step-by-step explanation:
Volume of a sphere = 4/3 pi r^3 r = 3 for this one
volume = 4/3 pi (3^2) = 36/3 pi = 12 pi units^3
Answer:
612
Step-by-step explanation:
Answer:
(-9, π/5 + (2n + 1)π)
Step-by-step explanation:
Adding any integer multiple of 2π to the direction argument will result in full-circle rotations, which are identities, so this family is equivalent to the give coordinates:
(9, π/5 + 2nπ), for any integer n
Also, multiplying the radius by -1 is a point reflection, equivalent to a half-turn rotation. Then add π to the direction for another half turn, and the result is another identity. So this too is equivalent to the given coordinates:
(-9, π/5 + (2n + 1)π), for any integer n
