Answer:

A. 9

Step-by-step explanation:

We use the remainder theorem.

The given function is

f(x) =  {x}^{3}  + 5 {x}^{2}  + sx + 6

If this function is divisible by x+2, then by the remainder theorem,

f( - 2) = 0

This implies that;

{( - 2)}^{3}  + 5( - 2 )^{2}  + s( - 2) + 6 = 0

We evaluate to get:

- 8 + 20 - 2s + 6 = 0

18 - 2s = 0

2s = 18 \\ s = 9

Step-by-step explanation:

<u>Formula:</u>

\boxed{a = 3.14(r)^{2} }

r represents the radius.

The radius is 1/2 of the diameter.

Since 1/2 of 16 is 8, 8 is our radius.

<u>Substitute:</u>

a = 3.14(8)^{2}

<u>Solve:</u>

a = 3.14(64)

a = 200.96in^{2}
