Answer:
Step-by-step explanation:
put it on a coorinate grid,
circle circumference = 2*pi*r = 100.53
so the arc 19.2/100.53 = about 0.15 times the circumference of the circle
0.15*2pi = angle AOB in radians = 0.97
length DE is like 7.44
angle DOE is approx 0.485 radians beacuse it's half of angle AOB
area of shaded region is 804.2477 probably. I'm not sure about this last one sorry I think my calculator messed up
We have to use proportion to solve this problem.
75% -------------------180
100% ---------------------x
crossmultiply
75*x=100*180
75x=18000 /:75
x=240 - its the answer
We have similar problem here
8%---------------------60$
100% ------------------x
crossmultiply now
8*x=60*100
8x=600 /:8
x=75 - its the answer
Answer:
the solution (x,y) are any x and y that satisfy the equation.
One possible solution is (0,3) or x=0, y=3.
Btw, x(squared) + y(squared) =3(squared)
is an equation of a circle centre (0,0) radius 3.
100^2/3
=³√1000^2
=³√1000000
Cube root the answer
³√1000000
=100. As a result, B is the correct answer. Hope it help!
