Answer : The measurement of a central angle is,
Step-by-step explanation :
Formula used for angle subtended by an arc is:
where,
s = arc length =
r = radius =
Now put all the given values in the above formula, we get:
Thus, the measurement of a central angle is,
Multiply the first equation by -4, to set up the x-coefficients to cancel. Take the value for y and substitute it back into either one of the original equations.
X+21/2 is the answer i got.
Answer:
rotating around y = 1 will make the sphere.
Step-by-step explanation:
Differences:
point slope form of line:
(a) equation is
where m is slope and (x1,y1) is a point
(b)This equation of line can be determined when two points are given
(x1, y1) and (x2,y2)
slope intercept form of line:
(a) equation is
where m is a slope
b is y-intercept
(b)This equation of line can be determined when y-intercept and slope are given
Similarilties:
(a) both are equation of straight line
(b) slope is always constant in both
