Answer:

B.)

87.92 feet

Explanation:

Given:

Area of the circular garden
= 615.44 ft^2

$\pi =3.14$

Finding the radius of the circle.

Area of the circle=
$\pi r^2$

$615.44=\pi *r^2$

$r^2=(615.44)/(\pi ) \\\\r^2=(615.44)/(3.14) \\r^2=196\\r=14 ft.$

Circumference of the garden:

$=2\pi r\\=2*3.14*14\\=87.92ft.$
