Question

find the sphere area of sphere of daimeter 3.5m?​

Answer 1

~Anzwer :-

$ \rm{Area~of~Sphere = 4\pi r^{2}}$

Here,

$ \rm{Radius = \frac{3.5}{2}}$

$= 1.75$

★ Area :-

$4\pi {r}^{2}$

$= 4 \times \frac{22}{7} \times {1.75}^{2}$

$= 4 \times 3.14 \times 3.0625$

$= 12.56 \times 3.0625$

$\rm{ = 38.465 \: {cm}^{2} }$

Answer 2

Answer:

38.5 m^2

Step-by-step explanation:

given diameter =3.5m

radius =d/2

r= 3.5/2

r=1.75m

sphere area of sphere = 4pi r^2

=4×22/7×(1.75)^2

=269.5/7

=38.5m^2
