Question

Find the radius of a circle and its area if its circumference is 16π cm

Answer 1

radius =8..........................

Answer 2

Answer:

radius of a circle is 8cm and it's area is

$200.96cm {}^{2}$

Step-by-step explanation:

circumference=2πr

16π=2πr

π get cancels both side

$\frac{16}{2} = r$

then radius is 8cm

$area \: of \: circle = \pi {r \\}^{2} \\ \ \frac{22}{7} \times 8 \times 8 \\ 3.14 \times 64 \\ 200.96 {cm}^{2}$
