What is the area of a circle formed by the intersection of a plane that is 24 mm from the center of a sphere whose radius is 30 mm.

Answer 1

Area=Pi*r^2 where
r^2=30^2-24^2
Draw an axial section of the sphere perpendicular to the plane

Answer 2

Is my answer 324 mm

Answer 3

did you forget the π ?

area = πr^2 = 18^2π = 324π

Answer 4

mm^2
