Answer:

25.12 millimeters is your answer.

Step-by-step explanation:

Circumference can be solved by using the equation:

c = 2πr or c = πd

Note that diameter (d) is equal to 8. Plug in 8 for d.

c = (8)(π)

Also note that π = 3.14. Multiply

c = (8)(3.14)

c = 25.12 millimeters.

25.12 millimeters is your answer.

Answer: 25.132

Step-by-step explanation: The circumference of a circle is always 2(pi)(r). With r being the radius which is ALWAYS half the diameter. So your radius is 4 millimeters. So multiply 2(pi)(4).

25.59

Step-by-step explanation:

The first thing that you will do is solve parenthesis (remember PEMDAS).

(32.45-4.8) - 2.06

(27.65) - 2.06

Then do the subtraction.

(27.65) - 2.06=

(2/5)+(3/(5x))=(x+5)/10
nasty fractions, we hates it forever

so

get rid of all those nasty fractions
multiply both sides by 10x
4x+6=x(x+5)
distribute
4x+6=x^2+5x
minus (4x+6) from both sides
0=x^2+x-6
factor
0=(x-2)(x+3)
set each to zero
0=x-2
2=x

0=x+3
-3=x

x=-3 and 2
