The three vertices of △abc are in quadrant i. if △abc is reflected in the x-axis, its image will lie in quadrant

The three vertices of △ABC are in quadrant I. If △ABC is reflected in the x-axis, its image will lie in quadrant IV

Hope it helps

Quadrant I is the top right section of a graph. The x-axis is the bold horizontal line usually in the middle of the graph. If you reflect a shape over it, it means you flip the figure across it to the other side.

The opposite side of Quadrant I is Quadrant IV, so the image of triangle ABC will lie in Quadrant IV.

The formula for area of a circle is: πr^2

r is half the diameter.

FE is the diameter: r = 20/2 = 10

Area of circle using FE = π10^2 = π * 100 = 314 square meters.

BE is a radius:

Area = π3.5^2 = π * 12.25 = 38.465  = 38.5 square cm ( rounded to nearest tenth).

AB is a radius:

Area = π11^2 = π * 121 = 379.94 = 380 square feet ( rounded off).

EF is a diameter

r = 12/2 = 6 meters

Area = π6^2 = π * 36 = 113.04 = 113 square meters ( rounded off).
