Find the circumcircle radius $R$ of a square if area $A = 8 cm$ .

Answer

$2$

Explanation

STEP 1: find side $a$

To find side $a$ use formula:

After substituting $A = 8 cm$ we have:

A = a^{2}

a^{2} = 8 cm

a = 8 cm

a = 22

STEP 2: find circumradius $R$

To find circumradius $R$ use formula:

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

After substituting $a = 22 cm^{0}$ we have:

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

R = \frac{4}{2}

R = 2
