Answer:

B. 4

Step-by-step explanation:

A direct proportion has the form

y = kx or k=y/x,

where k is the proportionality constant.

Let's test some points.

Second point

k = 8/2 = 4

Fifth point

k = 23/5.75 = 4

You will get the same result for every point, so the constant of proportionality is 4.

Answer:

38.485(correct to 5 significant figure)/ 12.25π

Step-by-step explanation:

$\pi(7 {}^{2} )( \frac{90degree}{360deree} )$

$= \pi(49)( \frac{1}{4} )$

=38.485(cor. to 5 sig.fig.)/ 12.25π

to find arc length of sector,we need to π(radius²)(sector's degree divided by 360 degree)
