The diameter is 6. Explanation:

radius: 3.14r^2

28.26=3.14r^2

28.26/3.14=r^2

r^2=9

r=3

and we know that diameter is two times the radius so:

3*2=6

diameter equals 6.

if you want to check it plug back in:

3^2 * 3.14 = 28.26

hope this helped :)

6x-3=3x+12<br>x= <br>What is the value of x in this equation​
goldenfox [79]

Answer:

x = 5

Step-by-step explanation:

6x - 3 = 3x + 12

-3x       -3x

_____________

3x - 3 = 12

    +3    +3

_____________

3x = 15

15 divided by 3 = 5

x = 5

You can double check this by replacing x with (5)

If it is right both sides should equal the same

6(5) - 3 = 3(5) + 12

30 - 3 = 15 + 12

27 = 27

This would prove that x = 5
