So we know the formula for circumference is C= πrd. And Circumference is the distance around a circle.
Example: C= circumference
C= 6.28 can u find the circles area :?
Step 1: divide 6.28 by 3.14 as the formula says.
Step 2 : after u divided u get 2 which is the diameter. and u divide the diameter by 2 because we are trying to get the radius because the formula for the circles area is
A= πr ^2
r = radius
r= 1
so what is 3.14 times 1
= 3.14
so 3.14 is the answer
I hope this helped u understand.
The answer is 0.071.
Hope it is right
Answer:
x=-4
Step-by-step explanation:
First, write the expression and distribute.
-2(2x+11)=5x+14
-4x-22=5x+14
Add one of the variables to the other side (it makes solving a lot easier). I'll add 4x to both sides because it won't result in a negative x.
-4x-22=5x+14
<u>+4x +4x</u>
-22=9x+14
Now, subtract 14 on both sides.
-22=9x+14
<u>-14 -14</u>
-36=9x
Divide both sides by 9.
-36=9x
<u>/9 /9</u>
-4=x or x=-4 (they both mean the same thing)
Have a wonderful day! I hope this helped :3
