Answer:
The lengths of the bases are 9 inches and 15 inches.
Step-by-step explanation:
The area of trapezoid is
Given that the height of a trapezoid is 8 in. and its area is 96 in².
Assume the bases of the trapezoid be b₁ and b₂.
Since one base of the trapezoid 6 in. longer than the other.
Let, b₁=b₂+6
The area of the trapezoid is
in²
in²
in²
According to the problem,
[ Multiplying 
]
Then, 
=9+6
=15 in
The lengths of the bases are 9 inches and 15 inches.

Answer:
42°
Step-by-step explanation:
3x + 54° = 180° [Supplementary angles]
=> 3x = 180 - 54
=> 3x = 126
=> <u>x = 42</u><u>°</u><u> </u><u>(Ans)</u>
The surface area and the volume of the cone is 816.4 km² and 7536 km³ respectively.
<h3>What is volume?</h3>
Volume is the capacity of an object.
To calculate the surface area and volume of the cone shown above, we use equation 1 and equation 2 respectively.
Formula:
- S = πr√(r²+h²)............. Equation 1
- V = πr²h.................. Equation 2
Where:
- S = Surface area of the cone
- V = Volume of the cone
- r = Radius of the base of thye cone
- h = Vertical height of the cone.
From the diagram,
Given:
- r = 10 km
- h = 24 km
- π = 3.14
Substitute these values into equation 1 and equation 2 respectively.
- S = 3.14×10[√(24²+10²)
- S = 31.4(√676)
- S = 31.4×26
- S = 816.4 km²
Also for the volume of tyhe cone
- V = 3.14×10²×24
- V = 7536 km³
Hence, The surface area and the volume of the cone is 816.4 km² and 7536 km³ respectively.
