Answer 2

Answer:

$\sf{Surface \: area \: of \: the \: sphere = 615.44 {cm}^{2}}$

Step-by-step explanation:

$\sf{Diameter = 14cm}$

$\sf{Radius = \frac{d}{2} = \frac{14}{2}cm =7cm}$

$\sf{Surface \: area \: of \: the \: sphere = 4\pi {r}^{2}}$

$= 4 \times 3.14 \times {(7)}^{2}$

$\sf{ = 4 \times 3.14 \times 7 cm\times 7cm}$

$\sf{ = 12.56 \times 49 {cm}^{2}}$

$\sf{ = 615.44 {cm}^{2}}$
