a circular native american dwlelling has a diameter of 24 feet. how much are inside the home? use 3.14 for { } (pi)

Respuesta :

Answer :

[tex]A = 452.16 \: {ft}^{2}[/tex]

step-by-step explanation:

From the question,

the diameter:

[tex]d = 24 \: ft[/tex]

The radius :

[tex]r = \frac{diameter}{2}= \frac{24}{2}=12 \: ft[/tex]

[tex]\pi = 3.14[/tex]

Area of a circle is given as

[tex]A = \pi {r}^{2} [/tex]

By substitution,

[tex]A = 3.14( {12}^{2} )[/tex]

[tex]\implies \: A = 3.14 \times 144[/tex]

[tex]\implies \: A = 452.16 \: {ft}^{2} [/tex]

Hence the area of the home is

[tex]A = 452.16 \: {ft}^{2}[/tex]
