Snowshoe hares have large hind feet that prevent them from sinking into soft snow. Their brown coats turn white in the winter to
velikii [3]

Answer:

This is an example of Morphological and structural adaptation

Explanation:

The morphological and structural adaptation is an anatomical adaptation, where living beings exhibit some characteristics that allow them to survive according to the environment in which they are, either promoting a camouflage, or resembling animals that are dangerous to frighten possible predators.

An example of this can be seen in the question above, where the hare, in order to survive and reproduce, allow the hair to become white as snow, and can camouflage themselves in the environment in which they are.

A circle with area 36 pi has a sector with a central angle of 11/6 pi radians what is the area of the cector
Vlad [161]

Answer:

The area of the sector is 33\pi.

Explanation:

A sector is a part of a circle that is formed by two radii (which forms a central angle), and an arc. The area of a sector (in radians) is given by:

                          = (θ ÷ 2\pi) × \pi r^{2}

where: θ is the central angle of the sector and r is the radius of the circle of which the sector is a part.

Area of a circle = \pi r^{2}. But the area of the circles was given to be 36\pi.

Area of the sector = (θ ÷ 2\pi) × area of the circle

                              = (θ ÷ 2\pi) ×36\pi

θ has been given to be \frac{11}{6}\pi.

Therefore;

   Area of the sector = (\frac{11}{6}\pi ÷ 2\pi) ×36\pi

                                   = \frac{11}{12} × 36\pi

                                   = 11 × 3\pi

                                   = 33\pi

The area of the sector is 33\pi.
