Question

solve it!! circumfrance of circle is 88cm. find its radius and diameter

Answer 1

Answer:

Step-by-step explanation:

Answer 2

circumference of circle
$= 2\pi \: r$

$\frac{2 \times 22 \times r}{7} = 88$

$r = \frac{88 \times 7} {44} = 14cm$

area of circle
$= \pi \: {r}^{2}$

$= 2 \times 14 \times \frac{14}{7}$

$= 28 \times 22$

$= {616cm}^{2}$
