A building is made of a cone and a right circular cylinder. The height of the cylinder is 210 cm and the height of the cone is 21 cm. Theradius of the base of the cylinder and the base of the cone is 14 cm. Find the capacity of the building. About the author Peyton
Answer: 133672 cm^3 Step-by-step explanation: Volume / Capacity of building – Volume of cone + volume of cylinder Volume of cone = [tex]1 \3 \: \: \pi r ^{2} h[/tex] = 1/3 × 22/7 × 14 × 14 × 21 = 4312 cm^3 Volume of cylinder = [tex]\pi \: r ^{2} h[/tex] = 22/7 × 14 ×14 × 210 = 129360 cm^3 Volume of building = 4312 + 129360 = 133672 cm^3 hope this will help u Reply
Answer:
133672 cm^3
Step-by-step explanation:
Volume / Capacity of building –
Volume of cone + volume of cylinder
Volume of cone =
[tex]1 \3 \: \: \pi r ^{2} h[/tex]
= 1/3 × 22/7 × 14 × 14 × 21
= 4312 cm^3
Volume of cylinder =
[tex]\pi \: r ^{2} h[/tex]
= 22/7 × 14 ×14 × 210
= 129360 cm^3
Volume of building = 4312 + 129360
= 133672 cm^3
