Question

what are the lateral and total surface areas and volumes of a frustum, a cone , a cylinder , a sphere and a right pyramid?Is there any easy way of remembering the formulae?​

Answer 1

HOPE ITS HELP U...............XD

Answer 2

Step-by-step explanation:

volume of frustum= 1/3x22/7(r2+R2)+rR

cone= 1/3x22/7xr3

cylinder= 22/7xr2xh

sphere = 4x22/7xr3

total surface area =

fustrum= 22/7x(r2+R2)x(r+ R)

cone = 22/7xrxl

cylinder= 2x22/7x r(r+h)
