Question

total surface area of an closed cone​

Answer 1

$\mathfrak{\large{\green{\underline{\underline{answer}}}}}</p><p>$

The surface area of a cone is equal to the curved surface area plus the area of the base:π r 2 + π L r , \pi r^2 + \pi L r, πr2+πLr,

where r denotes the radius of the base of the $\text \pink { cone }$ and L denotes the slant height of the $\text \blue { cone }$.

Answer 2

Answer:

• Total SA = πr(r+l)
• where pie is 22/7 or 3.14
• r is radius of the cone
• l is length of the cone
