given- circumference = 22cm
now,
- 22= 2×(22/7)×radius
- 22×7/22×2 =radius
- radius =7/2cm
- now volume of cone
- =1/3 × 22/7× r^2 ×h
- 1/3×22/7×(7/2)^2 ×(2×7/2)
- =89.83 cm^3

Answer:
89.83 cm^3
Step-by-step explanation:
The circumference of cone =2×pie×radius
22 = 2×22/7×radius
22×7=2×22×radius
154/44=radius
radius=3.5cm
diameter =2×radius
=2×3.5
=7cm
Height = Diameter = 7cm
Volume of cone = 1/3×pie×radius^2×height
=1/3×22/7×(3.5)^2×7
=22×(3.5)^2/3
=22×12.25/3
=269.50/3
=89.83 cm^3
