Answer:
the answer is 250
Step-by-step explanation:
u - v = <5, 2> - <2, - 3> = <5 - 2, 2 + 3> = <3, 5>
given a vector <u, v> then the magnitude is √ (u² + v² ) and it's angle of direction is
θ =
(
)
thus the magnitude of <3, 5> = √(3² + 5²) = √34 ≈ 5.83 ( to 2 dec. places )
Θ =
(
) = 59.04° ( to 2 dec. places )
Answer:
about 785.4
Step-by-step explanation:
The circumference of a circle is pi times the diameter:
C = πd
C = π·(250 ft) ≈ 785.4 ft

Most scientific or graphing calculators have the value of π built in. If yours doesn't, a value good for at least 6 significant figures is the ratio 355/113.
to answer the surface area for a cylinder you need to do 2 times 3.14 (pi) times the radius times the height. once you have that answer you need to do 2 times pi times the radius squared. then after you get both of those answers you add them together
it's c negative numbers are smaller
