Answer:

C= -14

Step-by-step explanation:

2(c+8)= -12 > divide both sides by 2

C+8= -6 > move c by itself

C= -6-8  > then subtract -6 and -8 and you will get -14

daser333 [38]

Options were missing in the question;

A water cup is shaped like a cone. It has a diameter of 3 inches and a slant height of 5 inches. About how many square inches of paper do you need to make a cup? Use 3.14 to approximate pi.

24 square inches

31 square inches

47 square inches

52 square inches

Answer:

24 square inches

Step-by-step explanation:

Given:

Diameter = 3 in

So we can say that;

Radius is half of diameter.

radius (r) = \frac{3}{2}=1.5\ in

Slant height (l) = 5 in

We need to find how many square inches of paper do you need to make a cup.

Solution:

Now according to question we required to find the amount of paper used to make cup.

Also Water cup is shaped liked cone.

Hence we can say that the base of cone is not covered since it will remain open.

So we will use Lateral surface area of the cone to find the paper requirement.

Now we know that;

Lateral surface area of cone is equal to π times radius times slant height.

framing in equation form we get;

A_L = \pi rl=3.14\times1.5\times5 = 23.55 in^2 \approx 24\ in^2

Hence We can say that 24 square inches of paper will be needed to make the cup.
