Answer:
Step-by-step explanation:
<em>m∠D</em> = 90° - 51° = <em>39°</em>
sin E = ⇒ DE = DF × sin E
<em>DE</em> = 18 sin51° ≈ <em>14.0 ft.</em>
cos E = ⇒ EF = DF × cos E
<em>EF</em> = 18 × cos51° ≈ <em>11.3 ft.</em>
Answer:
Surface area of the cube = 216 square units
Step-by-step explanation:
Let the length of a side of a cube = x unit
Diameter of the sphere inscribed in this cube = length of a side of the cube
Volume of the sphere =
Where r = radius of the sphere = units
36π =
36π =
36×24 = 4x³
x =
x = 6 units
Length of a side of the cube = 6 units
Surface area of the cube = 6×(Side)²
= 6×(6)²
= 216
= 216 square units
