Answer 1

15.7 m

220 m

2 m²

125.66meter.

Step-by-step explanation:

1.)

Diameter of garden = 5 meter

d = 5m

Radius, r = 5 /2 = 2.5m

Circumference = 2πr = 2π * 2.5 = 15.7 meter

2.)

Radius of circular bed = 35 m

Circumference = 2πr = 2π * 35 = 219.9 = 220 m

3.)

Diameter = 2 meters ; Radius = 2 / 2 = 1

Area = πr = π * 1² = 2m²

4.)

Radius = 20 m

Circumference = 2πr = 2π * 20 = 125.66meter
