Question

Calcule a área e o volume de uma esfera de raio =3

Answer 1

area=4πr^2

area=4.(3)^2π

area=4.9π

area=36πcm^2

volume =4/3.r^3.π

volume=36.π.3/3

volume=36πcm^3

Answer 2

Area

S = 4. π . 3²

S =  4 . 3,14 x 9 = 113,04 m²

Volume

V = 4/3 π.r³

V = 4/3  . 3,14 . 3³

V = 113,04 m³

V =
