Answer
300.8
Step-by-step explanation:
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
