Question

If area of a circle is 2464 sq.cm then find its circumference

Answer 1

Answer:

The circumference is 176 cm.

Step-by-step explanation:

Compute the value of the radius as follows:

$Area=\pi r^{2}\\2464=\pi r^{2}\\r^{2}=\frac{2464\times7}{22}\\r=\sqrt{784}\\=28$

Compute the circumference as follows:

$C=2\pi r\\=2\times\frac{22}{7}\times28\\=176$

Thus, the circumference is 176 cm.
