The area of a circle is 1441 m2. What is the diameter of the circle?

1 answer:

6 0

Hey there! I'm happy to help!

The area of a circle is the radius squared multiplied by pi (we will use 3.14). We already have the area, so we will go backwards.

1441÷3.14≈458.9171975

We find the square root.

√458.9≈21.42235275

Now we have our approximate radius. The diameter is twice the radius.

21.42235275×2=42.8447055

I don't know exactly if they want you to round it or not, but the diameter is somewhere around there.

Have a wonderful day! :D

Select the fraction that is the same as 42%

Rzqust [24]

Since percentages represent a part out of one hundred, we can start off by converting 42% to 42/100. Now that we have this, simplify the fraction so that it is in simplest form. This would be 21/50, which is your answer :)
