What is the circumference of the given circle in terms of ? a. 14 in.
b. 28 in.
c. 42 in.
d. 196 in.

b. 28 in.

Step-by-step explanation:

circumference of a circle = 2 r

whrere r is the radius of rhe circle

= 2 × × 14 in.

= 28 in.

that is option b

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
