There is a circular fountain in a park with a 10m radius lies alone in the center of a circular park with 200m radius . what is the total walking area available to visitors

The formula for the area of a circle is PI x radius^2

The park has a radius of 200m

The area of the park = PI x 200^2 = 125,600 square meters.

The radius of the fountain is 10m

The area of the fountain = PI x 10^2 = 314 square meters.

The area to walk ids the area of the park minus the area of the fountain:

125,600 - 314 = 125,286 square meters.

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

x=30
