Answer:

3051.08 cm squared

Step-by-step explanation:

The equation to find lateral surface area of a cone:

SA = pi r sqrt(h^2 * r^2)

Plug your values in.

SA = 3.14 * 9 * sqrt(144*81)

SA = 3.14 * 9 * 108

SA = 3051.08

The lateral surface area is 3051.08 cm squared.

Answer:

424.12cm^2

Step-by-step explanation:

make sure you have the radius, half of the diameter!

remember to use this formula! Lateral surface area = πrs = πr√(r2 + h2)

hope this helped!

r=radius

h=hight

s=slant

Chicken strips at a restaurant sell for the following prices: 4 pieces for $2.40 6 pieces for $3.00 How much do customers save p
const2013 [10]

Answer:

10 cents

Step-by-step explanation:

In order to answer this question we have to find how much each chicken strip costs individually.

Let's start with the 4 piece.

To find how much each piece costs we have to divide $2.40 by 4. Like this:

\frac{2.40}{4} = .60

In the 4 piece, every chicken strip costs .60 cents.

Now, let's do the 6 piece.

Like before we are going to divide $3.00 by 6.

\frac{3.00}{6} = .50

In the 6 piece, every chicken strip costs .50 cents.

Therefore, customers save 10 cents when they buy the larger quantity.

<em>I hope this helps!</em>
