Answer: a
Step-by-step explanation:
The diameter is 16m Because the diameter is twice the radius
31 is the answer because you would do 5 x 3 an that's 15 and if it's squared u technically add 15 a second time
Formula : 2 x pie x radius
1. 2x3.14x3=18.84in
2.2x3.14x6=36.48yd
3.2x3.14x4=25.12ft
4.2x3.14x12=75.36yd
