Question

Find the diameter of a circle with an area of 240.25(3.14) square millimeters

Answer 1

The diameter of the circle is 17.49

Answer 2

Answer:

The diameter of a circle with an area of 240.25 square millimeters is approximately:

• 17.49 millimeters.

Step-by-step explanation:

The area of a circle is usually calculated using the formula:

• Area of a circle = PI * radius of the circle ^ 2

You must remember that the radius is exactly half the radius, so you must clear the radius of the equation and finally multiply it by 2:

Solving for the radius of the formula gives:

• Circle radius = square root (Area of circle / PI)

When replacing with the provided data, you get:

• Circle radius = square root (240.25 mm ^ 2 / PI)
• Circle radius = 8.7449

As you remember, the radius must be multiplied by 2 to obtain the diameter, therefore:

• Circle diameter = 8.7449 * 2
• Circle diameter = 17.4898 about 17.49
