Answer:
f(-4)= 24
Step-by-step explanation:
-4(-4)+8 We need to multiply -4 and -4 and a negative times a negative is a positive.
16+8 Now it's easy math and we just add them
This gives us 24.

<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 :)
