Question

A circular flower bed is 24 meters in diameter and has a circular sidewalk around it that is 4 meters wide. Find the area of the flower bed in square inches.

Answer 1

Answer:
`A=710294.4\ in.^2`

Explanation:

Given

diameter of circular flower bed is
`d=24\ m`

radius
`r=(24)/(2)=12\ m`

width of sidewalk
`b=4\ m`

So area of flower bed is
`A=\pi r^2`

`A=\pi (12)^2`

`A=452.448\ m^2`

`1\ m^2=1550\ in.^2`

`A=710294.4\ in.^2`
