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! :)
