Ahula hoop has a three foot diameter how far will it travel in 6 revolution

Distance traveled in 6 revolution = 56.52 ft

Step-by-step explanation:

Formula:

Circumference  of circle = 2πr

r - Radius of circle

It is given that,

A hula hoop has a three foot diameter.

Diameter = 3 ft

Therefore the radius r = diameter/2 = 3/2 = 1.5 ft

To find the circumference of loop

r = 1.5 ft

Circumference = 2πr = 2 * 3.14 * 1.5 = 9.42 ft

To find the distance traveled in 6 revolution

Distance traveled in one revolution =  9.42 ft

Distance traveled in 6 revolution = 6 * 9.42 = 56.52 ft

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
