1 mile = 5280 feet which means the plane is flying at an altidude of 4.5 miles currently other than that refine your question.
Answer:
15 inches
Step-by-step explanation:
Volume of a pyramid = 1/3 x ( length² x height)
4500 = 1/3 x ( length² x height)
height = 1/2 x length
4500 = 1/3 x ( length² x 1/2length)
multiply both sides of the equation by 6
27000 = ( length² x length)
find the cube root of 27300
length = 30
height = 1/2 x 30 = 15in
Answer: area of the path alone is 178.98 ft²
Step-by-step explanation:
Since the circular garden is surrounded by a circular path, two circles are formed.
The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
Considering the circular garden,
Radius = 8 ft
Area = 3.14 × 8² = 200.96 ft²
Considering the circular garden and the circular path together,
Radius = 8 + 3 = 11 ft
Area = 3.14 × 11² = 379.94 ft²
Area of the path alone is the circular garden and the circular path together - area of circular path
It becomes
379.94 - 200.96 = 178.98 ft²
The circle will form a sphere. (See 1st figure attached)
The rhombus (it can also be a square) will form a 2 cones attached at the bottom. (See 2nd figure attached)
The rectangle will form a cylinder. (See 3rd figure attached)
The triangle will form a cone.
Answer: The third figure.
-8+3+-8--3
minusing a negativ means adding a positive
adding a negaative means minusing a positive
-8+3-8+3
-5-8+3
-13+3
-10
