   Determine the radius of a circle. Let's assume it's equal to 14 cm.

   Substitute this value to the formula for circumference: C = 2 * π * R = 2 * π * 14 = 87.9646 cm.

   You can also use it to find the area of a circle: A = π * R² = π * 14² = 615.752 cm².

   Finally, you can find the diameter - it is simply double the radius: D = 2 * R = 2 * 14 = 28 cm.

   Use our circumference calculator to find the radius when you only have the circumference or area of a circle.

If you wish to calculate the properties of a three-dimensional solid, such as a sphere, cylinder or cone, it's best to use our volume calculator.

 

         Hope this helped a little :)

39 divide (2+1) - 2 x (4+1)
Anvisha [2.4K]

Answer:

8-2x I think

Step-by-step explanation:

You would first divide 39 by 3, ( 2 + 1 = 3) and get 13.

You would next take 5 away from 13 and get 8.

Then you have your answer, because you cannot simplify it more because both the numbers do not have the same variable.

Bianca put a layer of packing tape around the top outside edges of a box to ship it. Which measurement represents the total amou
rjkz [21]

Bianca put a layer of packing tape around the top outside edges of a box to ship it.

The measurement that represents the total amount of packing tape that she used is - the perimeter of the top of the box

Perimeter is defined as the measurement of the outer lines or edges of any figure. As there is a box and only the outer edges are covered with tape, it means that Bianca has used the tape equaling the total perimeter of the top.

It can be more clear with this example

Suppose the box is rectangular with top dimensions 10 inches and 5 inches.

So, perimeter is length+width+length+width

or 2(length+width)

perimeter = 2(10+5) = 30 units. So, Bianca used 30 units of tape.
