A circular flower bed is 22 m in diameter and has a circular sidewalk around it that is 4 m wide. Find the area of the sidewalk in square meters. Use 3.14 for pi.
The area of the sidewalk is "blank" m to the power of 2
Plz answer will give brainiest plz i need help fast

The area of the blank M is 326.56m²

Step-by-step explanation:

This problem bothers on the mensuration of flat shapes

Given data

Diameter of flower bed d=22m

Radius of flower bed r= 11m

Width of side walk x =4m

To solve for the area of the blank we need to subtract the area of the side walk from the area of the flower bed

But we don't know the diameter of the side walk

Let the diameter of the side walk be D= diameter of flower bed +2(width of the side walk )

D= 22+2(4)

D=22+8

D=30m

Radius of side walk is R=30/2 =15m

Area of blank =area of side walk minus area of flower bed

Area of circle =πr²

Area of blank M = πR²-πr²

M= π(R²-r²)

M= 3.14(15²-11²

M=3.14(225-121)

M=3.14(104)

M= 326.56m²

The area of the blank M 326.56m²

M to the power of 2 =326.56²=106641.43

question:

could we have options?
