Answer:

Circumference= 31.42

Area= 78.5 cm²

Step-by-step explanation:

Formula for circumference of a circle= 2πr

$2 \times \frac{22}{7} \times 5 = 31.42$

Therefore, Circumference of the circle is 31.4 cm.

Formula for area of the circle = πr²

$\frac{22}{7} \times {5}^{2} = 78.5$

Therefore, Area of the Circle is 78.5 cm².
