Answer:
100 cm² or 314.16 cm²
Step-by-step explanation:
First, you should find the radius of the circle, which is half the diameter.
r = 10 cm
The area of the circle = r²
So you just need to plug in and multiply everything.
A = 10²
= 100 cm²
Usually, you can leave it in terms of pi, but otherwise
= 314.16 cm²
