<h3><u>Answer :- </u></h3>
- The total surfAce area of cone is <u>1244.57m².</u>
<h3><u>Step-by-step</u><u> </u><u>explanation</u><u> </u><u>:</u><u>-</u><u> </u></h3>
<u>To </u><u>find </u><u>:</u><u>-</u><u> </u>
- The total surface area of cone..
<h3><u>Solution :- </u></h3>
Given that ,
- The slant height of the cone = 21m.
- Diameter of it's base = 24m.
<h3><u>♦</u><u> </u><u>Radius is </u></h3>
<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>
- π = 22/7
- r = Radius ( radii )..
- L = Slant height.
<h3>According to the question :- </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 :)

Answer:
Well, 60 (minutes in an hour) divided by 12 (from the problem) is 5, so you have to multiply that 5 by the 5 from the problem to find that the train is going 25 (5*5) mph. Just double this for two hours, and you result in 50!
Step-by-step explanation:
Brad would catch up to Rachel 8 hours after Rachel left or 5 hours after Brad left. they would catch up when they had both driven 400 miles.
