Question

find the area of circle whose circumferance is 52.8 .​

Answer 1

Step-by-step explanation:

First circumference of the circle by the given data

then find area of the circle

Answer 2

Answer:

To find area of any circle firstly we need only the radius of the circle.

ln this question radius is not given but it is given indirectly as we can easily calculate the radius with the help of circumference as:-

$circumference = 2 \pi r = 52.8 \: units \\ \implies \: r = \frac{52.8}{2 \pi} = \frac{26.4}{ \pi}$

Now as we know that area of circle is equals to

$\pi {r}^{2} = \pi \times \frac{26.4} { \pi} \times \frac{26.4} { \pi} \\ = \frac{696.96}{ \frac{22}{7} } \\ = \frac{696.96 \times 7}{22} \\ = \frac{4878.72}{22} \\ = 221.76 \: sq.units \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed {\boxed{Answer}}$
