Step-by-step explanation:
"Deposition occurs when weathered rocks, soil, and sediments are carried by erosion to a new location and left there. Deposition happens when the forces carrying the sediments - wind, water, glaciers - are no longer strong enough to move the sediments. Rivers and streams fill with melting snow in the springtime."

The perimeter of triangle is: 14.15 units
Step-by-step explanation:
First of all we have to find the lengths of sides of triangles
Given
A(3, 1), B(2, -1), and C(-3, 2)
The distance formula will be used to find the lengths of sides

So,

The perimeter of triangle will be:

Hence,
The perimeter of triangle is: 14.15 units

Answer:
942 6/7 cm²
Step-by-step explanation:
Since O = Center of bigger circle, OA = Radius of bigger circle.
∴ Area of smaller circle - Area of bigger circle = Area of shaded part.
∴ Area of smaller circle = 22/7 × 10²
                                        = 22/7 × 100
                                        = 2200/7
                                        = 314 2/7 cm²
∴ Area of bigger circle = 22/7 × 20 ²
                                       = 22/7 × 400
                                       = 1257  1/7 cm²
∴ Area of shaded part = 1257 1/7 - 314 2/7
                                      =  942 6/7 cm²
