Answer:

1. D.)28.26 m^2

2.) A.)377 mm

4.) 615.75 square inches^3

Step-by-step explanation:

1.) Formula: π(r)^2

(3)^2=9

9π=28.27

2.) Formula for circumference: 2πr

D=120

Half the diameter is the radius: 60

60(2)=120

120(π)= 376.99

376.99 is close to 377

4.) Formula: (r)^2(pi)

D=28

R=14

14^2=196

196(pi)

615.75 square inches^3

Keep in mind, I used the symbol pi and not 3.14 so it's mostly accurate and a bit slightly off.

Hope this helps! :)
