Question

The perimeter of a semicircular pool is 72m.what is the area of the pool

Answer 1

Perimeter=72 m

ATQ;

$\frac{2\pi \times r}{2} = 72$
$\frac{22}{7} \times r = 72$
$r = \frac{72 \times 7}{22}$

$r = \frac{252}{11}$
So,now we know the radius.

From that we can take out the area of the semicircular pool.

Now,

$\frac{\pi \times r {}^{2} }{2}$
=9072/11 square meter.

Answer 2

Answer:

from that we can per metre of a semi-circular police 72 y m c a the matter of a semicircular police 72 matter
