Question

Caucle a área da circunferência A=π.R^2​

Answer 1

Resposta:

a)= pi.r²

a=pi.49

b) = pi.5²

area=pi.25

c)= pi.4²

area= pi.16

Answer 2

Oie, Td Bom?!

a)

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

$A = 3,14 \: . \: 7 {}^{2}$

$A = 3,14 \: . \: 49$

$A = 153,86 \: cm {}^{2}$

b)

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

$A = 3,14 \: . \: 5 {}^{2}$

$A = 3,14 \: . \: 25$

$A = 78,5 \: cm {}^{2}$

c)

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

$A = 3,14 \: .\: 4 {}^{2}$

$A = 3,14 \: . \: 16$

$A = 50,24 \: cm {}^{2}$
