Ina circle the circumference is
C = 2 * pi * r
Or
C = pi * d

D is the diameter and r is the radius depending on the situation you may choose the formula.

Since here we have the diameter known (20)

Then
C = 20 * pi

C = 20pi

What is 4x plus 6 plus 3 equals seventeen

Allushta [10]

The answer is 3.

the equation: 4x+6+3=17
4x+9=17
subtract 9 from both sides
4x=12
x=3

check by inserting 3 as x into the original equation

4*3+6+3=17

hope this helps!
