Answer:
x^2 + (y – 3)^2 = 36
Step-by-step explanation:
The standard equation of a circle with center at (h, k) and radius r is
(x - h)^2 + (y - k)^2 = r^2.
If the center lies on the y-axis, then h = 0: (x - 0)^2 + (y - k)^2 = r^2
If the circle diameter is 12, then the circle radius is 6, and so r^2 = 36
So, among the given equations, your
x^2 + (y – 3)^2 = 36 is correct (but only if you use " ^ " for exponentiation).
Answer:
x=3
Step-by-step explanation:
6×sin(30)=3
__________
Right angle opposite is your hypotenuse
30° opposite it is your opposite
SohCahToa
You're using Soh = Sin O/H but we dont have our opposite so we gotta times it instead with the side and sin(A) A would be your angle.
Answer: 3234 cubic units
Step-by-step explanation:
Volume of cylinder: πr²h
The diameter of the cylinder is 14 units so the radius is 7 units.
Now we'll substitute.
π = 22/7
h = 21
πr²h
π × 7² × 21
22/7 × 49 × 21 = 3,234
The volume is 3,234 cubic units.
To figure this out, you must use the Pythagorean theorem.
That is were you take the width of the opject, and square it (21 squared). and take the length of the object and square it (28 squared),
then add those together. (21 squared + 28 squared) = NUMBER
then take that number that you got, and find the square root of it. (<span>√NUMBER)
and that's your answer.
So it would be: 35 meters</span>
