Question

If the base radius and height of a cone are 6cm and 8cm respectively. Then what is the slant height of a right circular cone..​

Answer 1

Answer:

l=√h^2+r^2

l=√(6)^2+(8)^2

l=√36+64

l=√100

l=10 cm

Explanation:

Answer 2

Answer: Let r and l be the radius and the slant height of the solid right circular cone respectively.

r=35cm,l=37cm

Curved Surface area, CSA=πrl=π(35)(37)

CSA=4070sq.cm

Total surface area, TSA=πr(l+r)

=  

7

22

​  

×35×(37+35)

Thus, TSA=7920sq.cm
