WhatA circular flower bed is surrounded by a path 7 m wide. the diameter of the bed is 28 m. based on the given information, answer questions from 17 to 20 17. What is the diameter of the complete area ( flower bed + circular path)? ​

Answer 1

Answer:

Given that,

A circular flower bed is surrounded by a path 7 m wide path.

The diameter of the flower bed is 28 m.

We know,

radius of the flower bed=diameter/2

 

Where,

Diameter = 28m

Therefore,

28/2

=14

 

Now,

Radius of larger circle = Radius of flower bed + width of the path.

So,

14+7=21

 

Area of larger circle = πr²

π<21>^2

=41πcm^2

Area of smaller circle = πr²

π<14>^2=196πcm^2

Now, Area of path = Area of larger path - Area of smaller flower bed.

Where,

Area of larger path = 441π cm²

Area of smaller flower bed = 196π cm².

Therefore,

441π-196π

<441-196>π

245*π

245*22/7=35*22

=770m^2

Therefore, Area of the path = 770m².
