Note that rotation will not affect the shape and size of an object.
Rotation with respect to a point preserves the corresponding sides and the corresponding angles of the original image.
Hence, the statements
The corresponding angle measurements in each triangle between the pre-image and the image are preserved and
The corresponding lengths, from the point of rotation, between the pre-image and the image are preserved
are true.
Answer:
area of B or another side tell fast I will answer
A = L^2
A = L^2 = 2^2 + 4^2 (Pythagorean’s theorem)
A = L^2 = 20
Therefore the area of the square is 20 units square.
By definition, the volume of a quarter of a sphere is given by:

Where,
r: sphere radius
Substituting values we have:

Making the corresponding calculation we have:
Answer:
The volume of the quarter-sphere shaped tank is:
