Answer:
2.512
Step-by-step explanation:
the equation for circumference of a circle is
2(pi)r
plug in the 4
2(pi)4
combine like terms
8(pi)
you can leave the answer as is or you can multiply
8(3.14)= 2.512
the answer would be 2.512
***pi is equal to 3.14, if you are not allowed to keep your answer in terms of pi there is a pi button on the calculator you can use, or simply plug in 3.14
5 1/5 x 2/5 will be longer
Answer: 12.56 (insert units)
Step-by-step explanation:
radius = 2
so pi x r^2 = 3.14 x 2^2 = 12.56

Answer:
x = 5.5 (rounded)
Step-by-step explanation:
Equation: 700 = 132.69x - 25.96
Add 25.96 to both sides: 700+25.96 = 132.69x -25.96 + 25.96
Simplify: 725.96 = 132.69x
Isolate x
Divided both sides by 132.69: 
Simplify: x = 5.5 (rounded)
