Question 1 (1 point)

Answer 1

Answer:

9π units²

Step-by-step explanation:

To obtain an exact answer, use π, not an approximation such as 3.14.

A = πr² is the appropriate formula.

Here,

A = (3)^2·π units², or 9π units²

Answer 2

A=πr2=π·32≈28.27433
If you do pie times 3 squared you get 28.27433
