Area of the square = (9 m)^2 = 81 m^2

The four circular sectors combine to form a circle with diameter 9 m, hence radius 4.5 m.

Area of the circle = π (4.5 m)^2 = 20.25π m^2

Then the area of the shaded region is

81 m^2 - 20.25π m^2 ≈ 17.4 m^2

Melanies blue notebook cover is 20 centimeters by 30 centimeters. She has a sticker for each letter in her name. Each sticker is

gizmo_the_mogwai [7]

Find the surface area of her notebook.

30 + 30 + 20 + 20 = 100

Now find the surface area of the square stickers.

2 + 2 + 2 + 2 = 8

So this is the surface area of one square, now multiply it by 8.

8 * 7 = 56

This is the surface area of all the stickers, now subtract it to the surface area of the notebook:

100 - 56 = 44

So 44 centimeters of the notebook cover will still be showing.

What is the relationship between a reflection in a rigid motion

Paraphin [41]

A reflection is a type of rigid motion, along with translation, rotation, and glide reflection.
The relationship between them is the flipping of an object across a reflection line without changing shape or size, the only thing that changes is the position of the object.
