Answer:
Brady will need 25.12ft of edging
There are 50.24ft² in bradys garden
Step-by-step explanation:
radius = half of diameter
r = 8ft /2 = 4ft
To solve this problem we need to use the circumferenc formula of a circle:
c = circumference
r = radius = 4ft
π = 3.14
c = 2π * r
we replace with the known values
c = 2 * 3.14 * 4ft
c = 25.12ft
Brady will need 25.12ft of edging
To solve the second part of the problem we need to use the area formula of a circle:
a = area
r = radius = 4ft
π = 3.14
a = π * r²
we replace with the known values
a = 3.14 * (4ft)²
a = 3.14 * 16ft²
a = 50.24ft²
The area of the circle is 50.24ft²
