The number of cubic inches in the volume of a 6-inch high cylindrical can equals the number of square inches in the area of the
Svetradugi [14.3K]

Answer:

In inches, the radius of the can is <u>2</u>.

Step-by-step explanation:

Given:

The number of cubic inches in the volume of a 6-inch high cylindrical can equals the number of square inches in the area of the label that covers the lateral surface of the can.

Now, to find the radius of the can in inches.

Let the radius of can be r.

Height of can = 6\ inches.

<em>As given, the number of cubic inches of the volume of the cylindrical can equals the number of square inches in the area of the label that covers the lateral surface of the can.</em>

<em><u>So, </u></em>

<em><u>Volume of can = lateral surface area of can.</u></em>

Now, we put formula of volume and lateral surface area of cylinder:

\pi r^2h=2\pi rh

\pi \times r\times r\times 6=2\times \pi \times r\times 6

<em>Dividing both sides by </em>\pi \times r<em> we get:</em>

<em />r\times 6=2\times 6<em />

<em />6r=12<em />

<em>Dividing both sides by 6 we get:</em>

r=2.

Therefore, in inches, the radius of the can is <u>2</u>.

Compare the lengths of the segments. Rope C is _______ times as long as rope A. Write a multiplication equation
hichkok12 [17]

Answer:

Twice ; c = 2a ; a = c/2

Step-by-step explanation:

Since the drawing area has been gridded, accurate calculation could easily be performed ;

Rope A occupies 5 boxes

Rope C occupies 10 boxes

Hence,

10 boxes for C / 5 boxes for A

Therefore,

Rope C is Twice the length of Rope A.

If length of Rope A = a ; length of Rope C = c

Then, a multiplication equation for the length of Rope C equals ; c = 2a

Division equation :

a = c/ 2
