Question

Walking around the edge of a circular fourtain ,Ram noties that its circumference is 66m. Find the area of the fourtain region.

Answer 1

Answer:

$346.6 \: {m}^{2}$

Step-by-step explanation:

circumference:

$= 2 \: \pi \: r$

$66 = 2 \: \pi \: r \\ r = \frac{66}{2\pi} \\ r = \frac{33}{\pi}$

area:

$= \pi \: {r}^{2}$

$= \pi \times ( { \frac{33}{\pi}) }^{2} \\ = \pi \times \frac{1089}{ {\pi}^{2} } \\ = \frac{1089}{\pi} \\ = 346.639$
