Step-by-step explanation:

Given cylindrical cup have 2 in of radius and height of 6 in.

It is said that we need to cover the cup leaving top and bottom of cup.

To find how much material to cover:

After covering the cup, square box will be formed around the cup.

As shown in figure, Top view of square cup and box.

One face of box has length of diameter of cup = 2 in and height of box as height of cup = 6 in

Therefore, Area of one face of square box is length x height = 2 x 6 =12 in^{2}

Since, Box having 4 faces

Surface area of square box cover = 4 x area of one face of box

= 4x12=48in^{2}

djyliett [7]

Answer:

The actual water in the tank is 29.76 gallons.

Step-by-step explanation:

It is given that the farmer estimated amount of water is 25 gallons.

It is also given that he underestimate the water in tank by 16%.

Let the actual water in tank be x.

(1-\frac{16}{100})x=25

(\frac{100-16}{100})x=25

84x=25\times 100

x=\frac{2500}{84}

x=29.7619

x\approx 29.76

Therefore the actual water in the tank is 29.76 gallons.

PLEASE HELP ME <br> I don’t know how to solve this one please give me a good explanation

You have to use the distributive property, therefore you get 2x+13/3.

The next step is to do 2 x 5 because they gave us a number for the variable x. Then you have to do 2 x 13 which gives us 26.

10+26=36 and 36/3=12, hope I helped, Have a nice day! :)
