We have a circle with a diameter of 6.5 km. What is the area of this square ?​

Sagot :

Answer:

33.18

Step-by-step explanation:

The formula for the area of a circle is A = π r2, where r is the length of the radius of a circle. We can use our knowledge that a diameter is made up of two radii to understand that r = d/2. With this knowledge, you can rewrite the formula for the area of a circle as A = π (d/2)2.

Hope it made sense :)
