Answer:

Step-by-step explanation:

y varies directly as x

It means y=kx

y=18 when x=5

y=kx

18=k5

k=18/5

y=? When x=11

y=ky

Substitute the value of k

y=18/5(11)

=18×11/5

=198/5

=39.5

Circumference=2*pi*r or pi*d so if its 16pi you know that your diameter is 16 wich means your radius is 8 because d/2 is your radius. plug the 8 into the area formula wich gives you the formula pi*8^2. 8squared is 64. 64 times pi is 201. <span>or 64pi wich is the area of the same circle with the circumfernce of 16pi
