The radius is half of the diameter.
To find the circumference, use the equation C=2(pi)r or C=(pi)d.
r meaning radius. d meaning diameter.
(pi) is about 3.14 or 22/7
<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 :)
One stratagie you can use is called the big 7
Answer:
Step-by-step explanation:
First add 5x to 12x which becomes 17x and subtract 8 from 12 which becomes 4. So the answer is 17x+4!
