Given:
A circle with diameter 9 cm.
To find:
The area of the circle.
Solution:
The area of a circle is:
...(i)
Where r is the radius.
We know that, the diameter of a circle is twice than its radius.
The diameter of the given circle is 9 cm.


Substituting
in (i), we get




Therefore, the area of the given circle is 63.6.
Step-by-step explanation:
option C and E are the two equations
Option C, equation is 3x+2y= -14
LHS= 3(-6)+2(2) = -18+4 = - 14 =RHS
Again, option E equation x+y= -4
LHS= -6+2 =-4 =RHS
