Answer:
Height = 8 meters
Step-by-step explanation:
Given that
The volume V = 209 cubic meters Diameter = 10 meters
Radius r = 5 metres
How tall is the shed? The question is looking for the height of the cone
Using the formula for volume of a cone.
V = 1/3πr^2h
Where π = 3.14
209 = 1/3 × 3.14 × 5^2 ×h
209 = 3.14/3 × 25h
209 = 78.5h/3
h = 7.99 meters
h = 8 meters
Therefore, the shed is 8 meters tall.
The coefficient 6 represents the price for an hour of bike rental.
6.82 cm
1000=V=pi*r^2*h. 1000=pi*r^3, r=6.82 cm
x/2 = 6+4
x/2 = 10
x = 10*2
x=20
