12320 x 7/22x56 = 70
Slant height square = r square + height square.
70 cm = 56 cm + height square.
4900-3136= height square.
1764 = height square
So height = 42 cm
Slant height square = r square + height square.
70 cm = 56 cm + height square.
4900-3136= height square.
1764 = height square
So height = 42 cm

CSA of a cone = pi x r x l
12320 = 22/7 x 56 x l
l = 70 cm
l^2 = r^2 + h^2
h = 42 cm
