Answer:
the value of hi changes from 58 to 0:
h(t) = -4.9t^2 +19.8t
Step-by-step explanation:
If the initial height changes, then the term in the equation that represents that height will change. The initial height term is hi, so it changes from 58 to 0.
<u>To </u><u>find </u><u>:</u><u>-</u><u> </u>
Given that ,
<u>=</u>> Diameter / 2
=> 24 / 2
=> 12m
<h3>As we know that , </h3><u>Total surface area of cone = πr ( r + L ) .</u>
<h3><u>Where</u><u> </u><u>we </u><u>know</u><u>,</u></h3>The total surface of cone is,
<u>=> Total surface area = πr { r + L } ..</u>
• Therefore , The total surface area of cone is <u>1244.57m².</u>
Hope this helps you :)
