Question

2. Halla el area de las siguientes circunferencias,
radio
Pauza
radio 5 cm
radio 12 cm​

Answer 1

A =

$\pi \times {r}^{2}$

Radio = 5 cm

$a = \pi \times {5}^{2}$

$a = \pi \times {25}$

$a = 78.5398 \: cm$

Radio = 12 cm

$a = \pi \times {12}^{2}$

$a = \pi \times {144}$

$a = 452.3893$
