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.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
