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

Answer:

3.8 feet = radius (approx. value)

Step-by-step 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)

Hope it helps ⚜

Answer 2

given:

$area = 44 \: {ft}^{2}$

to find:

the radius of the rug rounded to the nearest tenth.

solution:

$a = \pi {r}^{2}$

$r = \sqrt{ \frac{a}{\pi} }$

$r = \sqrt{ \frac{44}{\pi} }$

$r = 3.74241$

$nearest \: tenth = 3.7 \: ft$

hence, the radius is 3.7 foot
