Acircle has a circumference of 3.143.143, point, 14 units.
what is the diameter of the circle?

The diameter is 1 unit

Step-by-step explanation:

The circumference is 3.14 units

C = pi * d

Using 3.14 for pi

3.14 = 3.14 d

Divide each side by 3.14

3.14/3.14 = 3.14 d/ 3.14

1 =d

1 unit.

Step-by-step explanation:

Given: The circumference of the circle = 3.14 units.

We know that the circumference of the circle is given by :-

, where d is the diameter of the circle.

Put the value of circumference , we get

Therefore, the diameter of the circle = 1 unit.

third option: 6x+8

step-by-step explanation:

we can see that the given question is a sum of series and the values of n vary from 0 to 3

the first term will be:

when n=0, [(0)*x+2] => (0+2) => 2

when n=1, [(1)*x+2] => (x+2) => x+2

when n=2, [(2)*x+2] => 2x+2

when n=4, [(3)*x+2] => 3x+2

so adding up all the terms will give us:

=2+x+2+2x+2+3x+2

=x+2x+3x+2+2+2+2

=6x+8

so,

third option is the correct answer ..

a² + b²= c²

24² + 7² = c²

c= 25
