Answer:
75.4 ft³
Step-by-step explanation:
Volume of a cone = πr²h/3
π = 3.14
radius, r = diameter / 2
= 6ft/2
= 3 ft
Height, h = 8 ft
Volume of a cone = πr²h/3
= (3.14 * (3)² * 8) / 3
= (3.14 * 9 * 8) / 3
= 226.08 / 3
= 75.36
Volume of a cone = 75.36 ft³
Approximately to the nearest tenth = 75.4 ft³

Answer:
20 boys
Step-by-step explanation:
30/3=10
10x2=20
3(24) + 2(24) + 5.39(24) = 72 + 48 + 129.36 = 249.36 ~ 249m^2
<span>Total Surface Area: </span>
<span>(add to the above) </span>
<span>2(1/2)(3)(2) = 6m^2 (area of the two triangles) </span>
<span>6 + 149 = 155m^2 </span>
