Question part points submissions used this exercise involves the formula for the area of a circular sector. find the area of a s
kolezko [41]
The formula for the area of a sector in radians is  A= \frac{1}{2}r^2 \theta,  where theta is the angle in radians.  For us, the formula looks like this:   A= \frac{1}{2}(9)^2* \frac{3 \pi }{5}.  Doing all the multiplication on that gives us  A= \frac{243 \pi }{10}.  Multiplying in pi and rounding to the nearest tenth gives us an area of 76.3 meters squared.  You can use the formula for the area of a sector with the angle in degrees as well.  Just replace the 360 degrees with 2pi and it works the exact same way.

Find the equation of the line that is parallel to the line <img src="https://tex.z-dn.net/?f=y%20%3D%20-%5Cfrac%7B3%7D%7B2%7Dx%2
ivann1987 [24]

A line parallel to your equation has the same slope, so it should be in the form:


y = (-3/2)x + b


To figure what "b" has to be, plug in the point (4,0) and solve:

0 = (-3/2)*4 + b

0 = -6 + b

6 = b

So the equation of the line is:

y = (-3/2)x + 6

PLS HELP I WILL GIVE BRAINLIEST
AnnyKZ [126]

So, you just have to recognize the line splitting the circle in half, line LJ.  So, if JC (arc) is 94, then do 180-94=86.  ∠LJC is an inscribed angle, so it's half of 86, which is 43°.

43° is your answer.
