——————-
4

Answer 1

$\sf Resposta: \: \red{\boxed{\frac{247\pi}{2}}}$

$\frac{\pi (25 \times 10 - 3) 2}{4}$

$\frac{\pi \times (250 - 3) \times 2}{4}$

$\frac{\pi \times (250 - 3)}{2}$

$\frac{\pi \times 247}{2}$

$\red{\boxed{\frac{247 \: \pi}{2}}}$

Outra forma:

$\sf \frac{\pi(25 \times 10 - 3) {}^{2} }{4}$

$\frac{\pi \times (250 - 3) {}^{2} }{4}$

$\frac{\pi \times 247 {}^{2} }{4}$

$\frac{\pi \times 61009}{4}$

$\red{ \boxed{\sf \frac{61009\pi}{4}}}$
