Answer:
if solved with original height of 9.8 = 9.33ft, if doubled from 9.8 to 19.6 ft in height = 19.37ft in height. That is a difference of 10.04ft.
Step-by-step explanation:
[tex]3^{2} + b^{2}=9.8^{2} \\ 9+b^{2} =96.04 \\ b^{2} = 87.04 \\\sqrt{b}^{2} = \sqrt{87.04} \\ b= 9.33[/tex]
[tex]3^{2} + b^{2} = 19.6^{2} \\9+b^{2} = 384.16\\b^{2} = 375.16\\\sqrt{b}^{2} = \sqrt{375.16} \\b=19.37\\\\19.37- 9.33= 10.04[/tex]
