The volume of the cone is 104.7 cubic feet. The volume of the half-sphere is 261.8 cubic feet and the area of the entire figure is 366.5 cubic feet.
Step-by-step explanation:
Step 1:
The figure consists of a cone and a half-sphere on top. We will have to calculate the volumes of the cone and the half-sphere separately and then add them to obtain the total volume.
Step 2:
The volume of a cone is determined by multiplying with π, the square of the radius (r²) and height (h).
The radius is 5 feet and the height is 4 feet.
The volume of the cone = cubic feet. Rounding this off, we get 104.7 cubic feet.
Step 3:
The area of a half-sphere is half of a full sphere.
The volume of a sphere is given by multiplying with π and the cube of the radius (r³).
Here the radius is 5 feet.
The volume of a full sphere cubic feet.
Step 4:
The volume of the half-sphere =
The volume of the half-sphere is 261.792 cubic feet. Rounding this off, we get 261.8 cubic feet.
Step 5:
The total volume = The cone's volume + The half sphere's volume,
The total volume cubic feet. By rounding this off to the nearest tenth we get 366.5 cubic feet.
Answer:
10 friends
Step-by-step explanation:
$18/$3 = 6
6 = number of friends that bought a ticket.
4 = number of friends who didn't buy a ticket.
end result, 6+4 = 10
