Question

Brandy is putting an 8 foot diameter circular floeer garden in his yard he will put plastic edging along the flowerbed how many feet of edging will brady need to enclose his flower garden, how man square feet are in bradys garden

Answer 1

Brady will need 25.12ft of edging

There are 50.24ft² in bradys garden

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
