Find the surface area of the ball
shown. Use 3.14 for a.
Radius is 16 cm


Sagot :

Ball is sphere

  • r=16cm

SurfAce area:-

  • 4πr^2
  • 4π(16)^2
  • 4π(256)
  • 1024πcm^2
  • 3215.36cm^2

Answer:

Formula

Surface area of a sphere:

[tex]\sf SA=4\pi r^2[/tex]  (where r is the radius)

Given information

[tex]\pi[/tex] = 3.14

r = 16

Final solution

Substitute given values into the equation and solve:

[tex]\sf \implies SA=4 \cdot 3.14 \cdot 16^2[/tex]

            [tex]\sf =3215.36 \ cm^2[/tex]
