Answer:
346585274.64
Step-by-step explanation:
The surface area of a sphere is
The radius is 3963
4 * 3.14 * 3963 * 6963 = 346585274.64
Answer:
96mm²
Step-by-step explanation:
a√ a²+ 4h²
4 √4² + 4(12)²
4 √4² + 4 (144)
4√4² + 576
97. 2 mm²
Answer:
x=-1

The axis of symmetry is along the vertex
The vertex is at (-1,-2)
The x coordinate is -1
x=-1
Answer:
a. ∠D'A'B'
Step-by-step explanation:
From the graph it is clear that the transformation doesn't affect the size and shape of the figure ABCD.
Only the coordinates of the points are changed with the length of each side remaining the same.
Hence the corresponding angle values will also remain unaltered.
∴ ∠DAB = ∠D'A'B'
