Answer:

289 m^2

Step-by-step explanation:

The diameter is 19 for the flowerbed, so the radius is

r = d/2 = 19/2 =9.5

We add the sidewalk

9.5+4 = 13.5

So the radius of the flowerbed and sidewalk is 13.5 m

We need to find the area of the flowerbed and sidewalk

A = pi r^2 = 3.14 ( 13.5)^2 = 572.265

The area of the flowerbed is

A = pi r^2 =   3.14 ( 9.5)^2 = 283.385

Subtract the two to find the area of the sidewalk

572.265-283.385 =288.88

Rounding to the nearest whole number

289 m^2

Answer:

289 m²

Step-by-step explanation:

First find the area of the flower bed

A=πr²= (3.14)(9.5)² = 283.385

Then get the area of everything including the sidewalk

A=πr²= (3.14)(13.5)² = 572.265

Then subtract and you'll get the area of just the sidewalk

572.265 - 283.385 = 288.88m²

FIRST PERSON WITH ANSWER RIGHT GETS BRANILY
Mumz [18]

Kim's age would be 24 and her sister would be 12 since her sisters' age is half of hers x would need to be multiplied by 1/2 to get her age.

x + x(1/2)=36 where x is 24

24 + 24(1/2) = 36

      24 + 12=36
