If x is the slant height of frustum of a cone, p and q are the base radii, find the ratio of tsa to csa

The ratio of TSA to CSA

Step-by-step explanation:

H x   slant height of frustum of a cone

Base radii

R q

r p

Total surface area of frustum of a cone is

Curved or lateral surface area of frustum of a cone is

Ratio will be of Total surface area of frustum of a cone and Curved or lateral surface area of frustum of a cone is
