The volume of cone is 24 or 75.398 cubic centimeters, if the cone has a radius of 3 centimeters and height of 8 centimeters.
Step-by-step explanation:
The given is,
Formula for volume of cone,
Where, B =
Volume,
From the given,
Radius, r = 3 centimeters
Height, h = 8 centimeters
volume,
Volume of cone, V= 24 (volume in terms of
)
( or )
Volume, V = (24 × 3.14 ) ( ∵ =3.14 )
V = 75.398 cubic inches
Result:
The volume of cone is 24 or 75.398 cubic centimeters, if the cone has a radius of 3 centimeters and height of 8 centimeters.
Answer:
The distance of the overpass above the ground is approximately 26.795 ft
Step-by-step explanation:
The parameters given are;
The distance from the overpass the engineer stands before determining the angle of elevation of the overpass from his standing point = 100 ft
The angle of elevation of the overpass as determined by the engineer from 100 ft = 15°
By trigonometric ratios, we have;
The opposite side to the 15° angle of elevation in the above case is the distance of the overpass above the ground
The opposite side to the 15° is the distance of the engineer from the base of the overpass
Therefore;
Tan(15°) the height of the overpass=
length
The distance of the overpass above the ground = 100 × tan (15°) ≈ 26.795 ft.
