calculating the area of a circle using 3.14 as the value for pi

Answer 1

To calculate the area of a circle, you can use the formula:

$$\text{Area}=\pi r^2$$

where $r$ is the radius of the circle and $\pi$ is approximately 3.14.

If you have the radius, you can substitute it into the formula. For example, if the radius $r$ is 5 units, the calculation would be:

$$\text{Area}=3.14\times (5^2)=3.14\times 25=78.5$$

So the area of a circle with a radius of 5 units would be 78.5 square units. You can use this method with any radius by substituting the value of $r$ into the formula.
