What is the radius? esther & jim plan to add a pond to there property. the area of the pond is 11 square meters. a) 3 b)√3 c)5/2 d)√7/2

Radius is the line drawn from the direct center of a circle to the outer edge

assuming the pond is a circle
area=pi times radius^2
area=11
11=pi times radius^2
aprox pi to 3.14
11=3.14 times radius^2
divide both sides by 3.14
3.503=radius^2

square root both sides
√3.5=radius which is also √5/2 or C

the answer is C
