what is the surface area of a conical grain storage tank that has a height of 24 meters and a diameter of 16 meters? round the a
Sauron [17]
<span>The basis of this cone is a circle with a diameter d = 16m. This information is sufficient to calculate
1. The surface of the wheel . We use the formula

</span>A =  \pi  r^{2} 
<span>
2. </span><span>the radius of the wheel needed to the formula for calculating the area of ​​a circle and the cone

d = 16m
1/2d = r = 1/2*16m = 8m
..................................................................................................
Area base
</span>P =  \pi  r^{2} =  \pi  (8m)^{2} = 64 \pi  m^{2}

A =  \pi rl 
<span>l - creates a cone = ?

</span><span>Height , forming a cone and the radius of a circle formed triangle . Two known sides is possible to calculate the third side ( the cone ) of the Pythagorean Theorem
</span>
a = r = 8cm
b = h = 24m
c = l = ?

a² + b² = c²
r² + h²  = l²
l = √ (r² + h²) = √ [ ( 8m)² + ( 24m)² ] = √ (64m² + 576m²) = √ (640 m²)= √ (8*8*10m²) = 8√10m

<span>The lateral surface of the cone

The total area of ​​the cone = <span>The base area of ​​the side surface of +

A = 64</span>√10πm² + 64πm² = 64πm² *(√10 + 1)
