Question

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

Answer 1

Answer:

Area of blank is 326.56m²

Step-by-step explanation:

For a better and pictorial understanding of this problem please see attached for your reference.

Given data

Let the flower bed be the small circle with diameter d= 22m

Radius of small circle = 22/2=11m

Let the side walk be the big circle with diameter D= 4+4+22=30m

Radius of big circle =30/2 = 15m

We know that the area of circle

A1=πr²

Hence area of flower bed

A1=3.14*11²

A1= 379.94m²

Also area of side Walk

A2= πr²

A2= 3.14*15²

A2= 706.5m²

Area of blank

A3= area of side walk - area of flower bed

A3= A2-A1

A3= 706.5-379.94

A3= 326.56m²
