Answer:
132
Step-by-step explanation:
Find Radius (r)
42/2 = 21
Plug 21 into Circumference Equation
2πr (In this case, π is 22/7)
Simplify
42 (22/7)
<u>132</u>
Answer:
21000
Step-by-step explanation:
To find estimate, round all the values to the nearest thousands
5,789 is 6000
8,356 is 8000
6,561 is 7,000
add.
6000+8000+7000
21000
Answer:
x = 2
Step-by-step explanation:
To start, you want to isolate x.
To do so, get all the x terms to one side.
2x + 1 = 4x - 3
Subtract -4x on both sides.
-2x + 1 = -3
Then, subtract 1 on both sides.
-2x = -4
Finally, divide -2 on both sides.
x = 2
Pythagorean theorem.
a^2+b^2=c^2
This means that the square of the length of the 2 legs of a right triangle added together = the square of the length of the hypotenuses or diagonal.
If you know 2 of the values in the 3 variables a,b,c what would you do to find the missing variable value?
I will not write the exact answers to this problem. I think you can figure how to write it out yourselves.
