Answer:

Radian is unit used for measuring plane angles, i.e 2D angles. Steradian is unit used for measuring solid angles, i.e 3D angles. radian = length of Arc/radius. steradian = area of cross-section/(radius^2) ❤️ ❤️ ❤️ ❤️ ❤️ ❤️ ❤️ ❤️ ❤️ ❤️ ❤️ ❤️ ❤️

Answer:

these are the basic fundamental quantities

RADIAN : it is the plane angle substended by a regular arc....

1 rad = 57.3°

⛔⛔⛔⛔⛔⛔⛔⛔⛔⛔⛔⛔⛔⛔⛔⛔⛔

steradian : it is a solid angle substended at the centre of a sphere subtended by a part of the surface equal in area to the square of the radius.

1 steradian = 4π radian

additional information...

dimensional formula for radian..➡️

.it is dimension less

same for steradian.... they r also dimension less

SI base units: 1 m2/m2
Unit system: SI derived unit
Unit of: Solid angle
