Answer:
the answer would be 0.
Step-by-step explanation:
this is because if you start with 0 multiply in half you get 0 then times it by 6 you still get 0. so the number sould stay the same. nothing would changed because you cant divide 0 by half. and anything multipled by 0 is still 0.
Answer: Choice B
Equation of a circle with (0,0) as its center and radius = 1
---------------------------------------------------------------
Explanation:
Recall that the unit circle is the equation
x^2 + y^2 = 1
This is a circle with center (h,k) = (0,0) and radius r = 1
It is in the form
(x-h)^2 + (y-k)^2 = r^2
We can write the first equation mentioned in the form sin^2(t)+cos^2(t) = 1
Using
x = cos(t)
y = sin(t)
t = angle
The point P(x,y) on the unit circle has an x coordinate of cos(t) and a y coordinate of sin(t). We can see this through drawing a right triangle.
NOOOOO I AM WRONG GGGGGGGG
Answer:
<h2>A = 2.25π</h2>
Step-by-step explanation:
The formula of an area of a circle:
r - radius
The formula of a circumference of a circle:
We have:
Substitute:
<em>divide both sides by 2π</em>
Substitute:
Answer:
234.784 ~ 235
Step-by-step explanation:
One side = 210
other side = 105
a2+b2 = c2
210 ^2 + 105 ^2 = c2
55125 = c ^2
c = 
= 234.784 ~ 235
hope its right!!!
