Answer: The correct answer is 7.12 m.

Step-by-step explanation:

The expression for the area of the circle is as follows;

A=\pi r^{2}

Here, A is the area of the circle and r is the radius of the circle.

Calculate the radius of the circle.

A=\pi r^{2}

Put A= 40 square meter and \pi=3.14.

40=(3.14) r^{2}

r=3.56 m

The expression for the diameter is as follows;

d= 2r

Here, d is the diameter of the circle and r is the radius of the circle.

Put r= 3.56 m.

d= 2(3.56)

d= 7.12 m

Therefore, the closest answer to the measure of the diameter of the circle is 7.12 m.

Let n be a natural number. Show that 3 | n3 −n
Vladimir [108]
Let n=1. Then n^3-n=1^3-1=0. By convention, every non-zero integer n divides 0, so 3\vert n^3-n.

Suppose this relation holds for n=k, i.e. 3\vert k^3-k. We then hope to show it must also hold for n=k+1.

You have

(k+1)^3-(k+1)=(k^3+3k^2+3k+1)-(k+1)=(k^3-k)+3(k^2+k)

We assumed that 3\vert k^3-k, and it's clear that 3\vert 3(k^2+k) because 3(k^2+k) is a multiple of 3. This means the remainder upon divides (k+1)^3-(k+1) must be 0, and therefore the relation holds for n=k+1. This proves the statement.
