CSA of cone =πrl=12320cm²
radius=56cm
Therefore,
12320=22/7*56*l
12320*7/22*56=l
l=70cm
As we know l=slant height
Therefore,
l²=b²+h²
70²=56²+h²
4900-3136=h²
h=√1764
h=42cm........
radius=56cm
Therefore,
12320=22/7*56*l
12320*7/22*56=l
l=70cm
As we know l=slant height
Therefore,
l²=b²+h²
70²=56²+h²
4900-3136=h²
h=√1764
h=42cm........
