Answer :

$A = 452.16 \: {ft}^(2)$

Explanation:

From the question,

the diameter:

$d = 24 \: ft$

The radius :

$r = (diameter)/(2)= (24)/(2)=12 \: ft$

$\pi = 3.14$

Area of a circle is given as

$A = \pi {r}^(2)$

By substitution,

$A = 3.14( {12}^(2) )$

$\implies \: A = 3.14 * 144$

$\implies \: A = 452.16 \: {ft}^(2)$

Hence the area of the home is

$A = 452.16 \: {ft}^(2)$
