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

4pi 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.

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
