The radius of the circular garden whose circumference is 122.46 feet is: 19.5 feet.
<h3>What is the Circumference of a Circle?</h3>
Circumference = 2πr, where r is the radius of the circle.
Given the following:
- Circumference = 122.46 feet
- Radius (r) = ?
- π = 3.14
122.46 = 2(3.14)(r)
122.46/2(3.14) = r
r = 19.5 feet.

Answer:
B
Step-by-step explanation:
The height to height ratio of the 2 rectangles = 21 : 7 = 3 : 1, that is
The sides of the red rectangle are one third of the corresponding sides in the blue rectangle, thus
w = 34 ÷ 3 ≈ 11.33 ( to 2 dec. places ) → B
