Question

1. Find the curved and total surface area of the cone whose height is 8 cm and radius of base 6 cm​

Answer 1

Answer:

radius of base of the cone = 6cm

height of the cone = 8cm

curved surface area of the cone = πrl

l = √ r^2 + h^2

l = √ 6^2 + 8^2

l = √ 36 + 64

l = √ 100

l = 10

=> 22/7 × 6 × 10

=> 220 × 6/7

=> 1320/7

=> 188.5...

total surface area of the cone = πr ( r + l )

=> 22/7 × 6 ( 6 + 10 )

=> 132/7 ( 16 )

=> 18.8 ( 16 )

=> 300.8
