Curved surface area of cone = πrl
251.2 =3.14× 8 × l
l= 251 .2÷ (3.14×8)
l=251.2÷25.12
l= 2512÷251.2
l=10
Slant height is 10 cm
HEY NOTE HERE AS curved surface area is
251.2 =3.14× 8 × l
l= 251 .2÷ (3.14×8)
l=251.2÷25.12
l= 2512÷251.2
l=10
Slant height is 10 cm
HEY NOTE HERE AS curved surface area is
