Find a volume of the following solid figures. Write your answer on you answer sheet. Use 3.14 for the value of pi (π). Show your solution and encircle your final answer

17.-18.

Solution:

  • [tex] \longrightarrow \sf{V = \frac{ \pi r^2 h}{3}} [/tex]
  • [tex] \longrightarrow \sf{V = \frac{3.14 \times 9m^2 \times 15m}{3}} [/tex]
  • [tex] \longrightarrow \sf{V = \frac{3.14 \times 81m \times 15m}{3}} [/tex]
  • [tex] \longrightarrow \sf{V = \frac{3815.1m}{3}} [/tex]
  • [tex] \longrightarrow \sf{V = \green{1271.7m^3}}[/tex]

[tex]\therefore[/tex] the volume of a cone is 3,815.1m³

19.-20.

Solution:

  • [tex] \longrightarrow \sf{V = \pi r^2 h}[/tex]
  • [tex] \longrightarrow \sf{V = 3.14 \times 42cm^2 \times 50cm}[/tex]
  • [tex] \longrightarrow \sf{V = 3.14 \times 1764cm \times 50cm}[/tex]
  • [tex] \longrightarrow \sf{V = 3.14 \times 88200cm}[/tex]
  • [tex] \longrightarrow \sf{V = \green{276948m^3}}[/tex]

[tex]\therefore[/tex] the volume of a cylinder is 276,948cm³
