The composite figure comprises of a cone balanced on top of cylinder
Step-by-step explanation:
The composite figure is formed from a cone and a cylinder with the same base radius, Let the base radius be r
Then the volume of the cone will be 
Then the volume of the cylinder will be 

The total volume of the composite figure will be V, where


let the height of cone and cylinder be same
The volume of the composite figure will be 

Hence 
Thecomposite figure comprises of a cone balanced on top of cylinder
Answer:

x = 0.36
Step-by-step explanation:
5x/3 + 2/5 = 1
5x/3 + 2/5 - 2/5 = 1 - 2/5

5x/3 × 3 = 0.6 × 3
5x = 1.8
5x ÷ 5 = 1.8 ÷ 5

x = 0.36
Answer:
8.2
Step-by-step explanation:
Area of triangle is calculated by multiplying height to the base and that divided by two
20 × h ÷ 2 = 56^2
h = 5.6
The square length of CD is equal to sum of square length of height and base
6^2 + 5.6^2 = CD^2
CD = 8.2
