Answer:

16 pi unit^2

Step-by-step explanation:

The diameter is 8 so we can find the radius

The area is given by

A = pi r^2

A = pi ( 4)^2

A = pi *16

Answer:

x = 1

Step-by-step explanation:

Given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 12 when x = - 2, then

k = $\frac{y}{x}$ = $\frac{12}{-2}$ = - 6, thus

y = - 6x ← equation of variation

When y = - 6, then

- 6 = - 6x ( divide both sides by - 6 )

x = 1
