Answer:
113.1
Step-by-step explanation:
Write down the equations on the top of your paper; it could help you throughout your homework.
The equation for circumference is 2 times pi, times the radius.
The Radius is the diameter times two.
2 times 9=18, so therefore the radius is 18.
Once you have that done, just put in your calculator 2 times pi times 18.
X+1=10
move +1 to the other side
sign changes from +1 to -1
to get X by itself
X+1-1=10-1
X=10-1
Answer:
X=9
Answer:
0.000083
Step-by-step explanation:
When you multiply by 10^-5, you're really multiplying by 0.00001. This multiplied by 8.3 is 0.000083. It also means that you just move the decimal place in 8.3 to the left five times, where you'll get the same answer.
No real way to solve it, with the knoledge of the perfect squares (1,4,9,16,25,49 ect) you can do the simple ones but more complicated ones require a calculator to solve it in decimal form
