Area of circle = πr²

Hence the area of the given circle is 616 cm².

Step-by-step explanation:

Answer 2

Answer:

here's ur answer mate

Step-by-step explanation:

$diameter = 28 \\ radius = \frac{diameter}{2} \\ r = \frac{28}{2} \\ r = 14 \\ area = \pi {r}^{2} \\ a = \frac{22}{7} \times {14}^{2} \\ a = \frac{22}{7} \times 196 \\ a = 22 \times 28 \\ a = 616$
