Suppose the radius of a circle is \color{purple}{2}2start color purple, 2, end color purple units. What is its circumference?

or 12.57 units

Step-by-step explanation:

It is given that the radius of a circle is 2 units.

We need to find the circumference of the circle.

The formula for circumference of a circle is

where, r is the radius of the circle.

Substitute r=2 in the above formula.

Here,

Therefore, the circumference of the circle is or 12.57 units.

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
