Area of a circle = (pi)(radius squared)
A of Circle X= (3.14)(18cm/2)squared
We need to divide the diameter in half to get the radius.
A of Circle X= (3.14)(9) squared
A of Circle X= (3.14)(81)
A if Circle X= 254.34 cm
A of Circle Y= (3.14)(31cm/2)squared
We need to divide the diameter in half to get the radius.
A of Circle Y= (3.14)(15.5) squared
A of Circle Y= (3.14)(240.25)
A if Circle Y= 754.39 cm
Find the difference in Area:
=Circle Y - Circle X
=754.39 - 254.34
=500.05 cm difference
Circle Y has the greater area of 754.39. It it greater than Circle X by 500.05 cm

Answer:
and 
Step-by-step explanation:
Assume that the terminal side of thetaθ passes through the point (−12,5).
In ordered pair (-12,5), x-intercept is negative and y-intercept is positive. It means the point lies in 2nd quadrant.
Using Pythagoras theorem:
Taking square root on both sides.
In a right angled triangle
In second quadrant only sine and cosecant are positive.
