Could you guys help me find the area of these please? i don't understand how to do this
vova2212 [387]

Answer:

for 9, the answer is 246.49

Step-by-step explanation:

This is area of a circle correct?

The formula is PI x radius squared.

3.14 x the radius, which is 5, squared

I am re-editing this

so sorry the answer is actually 78.54

The reason why it is 78.54 is that you need to square the radius before multiplying with PI.
