Question

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

Answer 1

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
