Answer:
Radius = 2.
Step-by-step explanation:
We have been given equation of the circle which is 
.
Now we need to find the radius of the given circle .
To find that let's compare with the formula of the circle with standard equation of the circle 
, where r is the radius.
We get 
take square root of both sides.
Hence radius of the given circle is r = 2.
Answer:
y- intercept = - 10 or (0, - 10 )
Step-by-step explanation:
to find the y-intercept, that is where the graph crosses the y- axis let x = 0 in the equation
f(0) = - 
(3)³ - 1
= - × 27 - 1 = - 9 - 1 = - 10

Answer:
Astronomers.
Step-by-step explanation:
In many, many ways we can use geometry in astronomy. One of the most or important example is that when astronomers find the distance between the different celestial bodies and they also find the tilt of any planet they uses geometry .
And in this field other uses of geometry when planets orbiting around the sun or satellites orbiting around there planets astronomers uses geometry to find the speed and velocity of the planets.
