What Is The Area Of A Circle If The Diameter Is 7cm?

What is the area of a circle if the diameter is 7cm?

 

Answer:

12.25π cm²

Step-by-step explanation:

Area of a Circle = πr² where r = radius.

We know 2r = d where d = diameter.

Since the diameter is given, we can divide it by 2 to get the radius. That is 7 / 2 = 3.5 cm.

Now solving for the area:

πr²

= π(3.5)²

= 12.25π cm²

Hope this helps!
