Question

2. Find the radii of the circle for the given areas.
a. 264 cm2
b. 308 m2
c. 182.12 m2​

Answer 1

Step-by-step explanation:

a. A=264

$\pi {r}^{2} = 264$

$\frac{22}{7} \times {r}^{2} = 264$

${r}^{2} = 264 \times \frac{7}{22}$

${r}^{2} = 84$

$r = \sqrt{84}$

$r = 9.16 \: cm$

Answer 2

Step-by-step explanation:

Step-by-step explanation:

a. A=264

\pi {r}^{2} = 264πr
