What is the radius of a circle with a area of 100 pie square feet and use the formula a= pie r 2

The formula is A = π r^2

The area is given as 100π square feet.

replace A with 100π:

100π = π r^2

Divide both sides by π:

100 = r^2

Take the square root of booth sides:

r = √100

r = 10

The radius is 10 feet.

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.
