X 1 2 3 4 y 5 10 15 20 What's the constant?

DiKsa [7]

Answer:

x ---> 1

y ---> 5

Step-by-step explanation:

We are given paired values for two variables x and y and we are to determine the constant number by which each term is increased such that they are in a proportional relationship.

For x, we have the following paired values:

$x: 1, 2, 3, 4$

So here the difference between each consecutive term is 1 so the constant is 1.

And for y, we have:

$y: 5, 10, 15, 20$

In this case, the difference between each consecutive term is 5 so the constant is 5.

Anybody can help?????

Vikentia [17]

The formula of an area of a circle:

$A=\pi r^2$

r - a radius

We have r = 14m. Substitute:

$A=\pi\cdot14^2=196\pi\ m^2$

If you want an approximate area, you can accept $\pi\approx3.14$

Then:

$A\approx196\cdot3.14=615.44\ m^2$
