314.2 cm^2
Step-by-step explanation:

With r = 10 cm, r^2 = 100 cm^2, and so the area of this circle is 314.2 cm^2, to the nearest tenth.
If I’m correct this is supposed to be a decimal ( here we use the dot not the comma ) but if so then 32.52 a good way to remember is 5 or more let it sore (meaning round up) four or less let it rest (meaning it stays the same)
