How do you calculate the area of a circle? area of a circle is equal to the diameterdiameter squaredradiusradius squared times diameterheightpiwidth.

The answer is:

or

We can calculate the area of any circle using the following formula:

Where,

π, is a constant used to calculate the area of the circle.

radius, is the distance from the center to any point of the circle.

Also, we have that:

So, we can rewrite the equation by the following way:

Have a nice day!

Use formula:

Step-by-step explanation:

We need to find about how to calculate the area of a circle.

And match with the given choices. Where given choices are:

Area of a circle is equal to the diameterdiameter

squaredradiusradius squared times diameterheightpiwidth.

I'm not sure what exactly you have typed as choices are not written in proper way.

But I can still answer that.

You just need to apply formula of the area of circle which is given by:

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
