<h3>3D shapes</h3>
- Cube Cuboid
- Sphere Square-based pyramid
- Cylinder Triangular prism
- Pentagonal pyramid Hexagonal prism

<em><u>A solid of revolution is a three-dimensional figure obtained by rotating a two-dimensional figure (or curve) around a straight line (called the axis) that lies in the same plane. ... Since the triangle's interior is shaded, it creates the interior of the cone, creating a solid figure.</u></em>
<em><u>Three dimensional shapes are obtained by rotating the two dimensional shapes. When a circle is rotated we get sphere; when a triangle is rotated we get cone; when rectangle or square is rotated we get cylinder</u></em>

Answer:
13.7 cm²
Step-by-step explanation:
area of yellow region = area of square - area of 4 quarter circles
area of square = 8² = 64
area of 4 congruent quarter circles = area of circle
area of circle with radius = 4
A = π × 4² = 16π
yellow region = 64 - 16π ≈ 13.7 cm²
X=area of the country A
y=area of the country B
we saggest this system of equations:
x+y=178,973
x=y+373
we solve this system of equations by substitution method.
(y+373)+y=178,973
2y=178,973-373
2y=178600
y=178,600/2=89,300
x=y+373
x=89300+373=89,673
answer:
area of the country A=89,673 Km²
area of the country B=89,300 Km²
To check
The combined land area of the countries A and B is =89,673 Km²+89,300 Km²=178,973 Km²
Country A (89,673 Km²) is 373 Km² more larger than country B (89,300 Km²).
89,673 Km²=89,300 Km²+373 Km²
