A figure has a perimeter of 40 units and an area of 100 square units. Which of the following describes the new perimeter and area after the figure is dilated by a scale factor of 1/2? * a. Perimeter: 20 units; Area: 50 squared units
b. Perimeter: 20 units; Area: 25 squared units
c. Perimeter: 80 units; Area: 25 squared units
d. Perimeter: 80 units; Area: 200 squared units

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.

this cant be answered without the graph. you may need to add it.

answer is 270 degrees: -

to convert radians to degrees you multiply by 180/π

9π/ 6 * 180 / π

=   9 * 180 / 6

= 9 * 30

=   270 degrees   answer
