Answer 1

Respuesta:

r = 3 cm

$4\pi {3}^{2} = 36\pi = 113.0973 \: {cm}^{2}$

r = 8 cm

$4\pi {8}^{2} = 256\pi = 804.2477 {cm}^{2}$

r = 12 cm

$4\pi {12}^{2} = 576\pi = 1809.5573 {cm}^{2}$

r = 11 m

$4\pi {11}^{2} = 484\pi = 1520.5308 {m}^{2}$

r = 2.4 m

$4\pi {2.4}^{2} = 23.04\pi = 72.38229474 {m}^{2}$

r = 0.015 m

$4\pi {0.015}^{2} = 0.0009\pi = 0.002827433 {m}^{2}$
