Question

Ikea has a cute rug on sale with an area of 44 square feet. What is the radius of the

rug rounded to the nearest tenth of a foot?

Answer 1

given:

`area = 44 \: {ft}^(2)`

to find:

the radius of the rug rounded to the nearest tenth.

solution:

`a = \pi {r}^(2)`

`r = \sqrt{ (a)/(\pi) }`

`r = \sqrt{ (44)/(\pi) }`

`r = 3.74241`

`nearest \: tenth = 3.7 \: ft`

hence, the radius is 3.7 foot

Answer 2

3.8 feet = radius (approx. value)

Explanation:

Area of the rug = 44 feet²

Radius = r = ?

Take π = 22/7

Area = πr²

44 = 22/7 × r²

44 × 7/22 = r²

14 = r²

√14 = r

3.8 feet = radius (approx. value)
