Answer:
54 miles per hour.
Step-by-step explanation:
Just divided 621 by 11.5.
You would take 621 and divide that by 11.5 and you would get 54 mph I believe, if I am wrong please let me know so I can take down my answer! have a great and God blessed day! :D
530.929158457
13x13= 169 x pi= 530.929158457
total area = 99m² + 39.4m²
= 138.4m²
=
38.64=9.2h/2
38.64=4.6h
h = 38.64/4.6
h = 8.4
thats it
