Answer:

2.57x10^4 is 100,000 Greater that 2.57x10^-1

Step-by-step explanation:

2.57x10^4 has a power by 4 which means

10^4 = 10,000

and 2.57x10^-1 has a power by -1 which means

10^-1 = 0,1

therefore 2.57x10^4 is 100,000 Greater that 2.57x10^-1

Taiga wants to make a circular loop that she can twirl around her body for exercise. He will use a tube that is 2.5 meters long.

Travka [436]

Answer: 0.796 meters

Step-by-step explanation:

Circumference of circle = $2\pi r$ , where r=radius

Here, Circumference of loop = 2.5 meters

i.e. $2\pi r=2.5$

$\Rightarrow\ r=\dfrac{2.5}{2\pi}$

$\Rightarrow\ r=\dfrac{2.5}{2\times\dfrac{22}{7}}\\\\\Rightarrow\ r=\dfrac{2.5\times7}{2\times22}\\\\\Righttarrow\ r=0.398\ m$

Diameter = 2r = 2(0.398) = 0.796 meters

Hence, The diameter of Taiga's exercise hoop = 0.796 meters
