Circumference = 66 m
2πr = 66
=> r = 66/2π = 33/π = 33×7/22 = 10.5 m
Volume of cone
= 1/3πr²h
= 1/3 × 22/7 × (10.5)² × 12
= 1386 m³
2πr = 66
=> r = 66/2π = 33/π = 33×7/22 = 10.5 m
Volume of cone
= 1/3πr²h
= 1/3 × 22/7 × (10.5)² × 12
= 1386 m³

circumference =66m
r=66/2TT
33/TT
33×7/22=10.5
VOLUME =1/3×TT×r×r×h
1/3×22/7×10.5×10.5×1002
=1386msq
r=66/2TT
33/TT
33×7/22=10.5
VOLUME =1/3×TT×r×r×h
1/3×22/7×10.5×10.5×1002
=1386msq
