Answer:
10 ft²
Step-by-step explanation:
Recall that the volume of a uniform cylinder may be defined by the formula:
Volume = Base Area x Height
In our case we are given
Volume = 15 ft³ and Base Area = 1.5 ft
Substituting these known values into the formula gives:
Volume = Base Area x Height
15 = Base Area x 1.5
Base Area = 15 / 1.5
Base Area = 10 ft²
B is true; pi= ~3.14. 3+4 is equal to 7, so because pi is greater than 3, pi+4>7
The ground, the building, and the ladder form a right triangle, in which
the leaning ladder is the hypotenuse.
For the angle between the ladder and the ground, the 4-ft along the ground
is the side adjacent to the angle, and the 7-ft ladder is the hypotenuse.
(adjacent side) / (hypotenuse) = cosine of the angle.
Cosine(a) = 4/7 = 0.57143... (rounded)
Angle 'a' = <em>55.15 degrees</em> (rounded)
