Find the area $A$ of a square if circumcircle radius $R = 6 cm$ .

Answer

$72 cm^{2}$

Explanation

STEP 1: find side $a$

To find side $a$ use formula:

R = \frac{2 \cdot a}{2}

After substituting $R = 6 cm$ we have:

6 cm = \frac{2 \cdot a}{2}

2 \cdot a = 6 cm \cdot 2

2 \cdot a = 12 cm

a = \frac{12 cm}{2}

a = 62 cm

STEP 2: find area $A$

To find area $A$ use formula:

A = a^{2}

After substituting $a = 62 cm$ we have:

A = (62 cm)^{2}

A = 72 cm^{2}
