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!
