Question

What is the formula of curved surface area and volume if frustum?​

Answer 1

$\huge\bigstar\underline\mathfrak{Answer:-}$

$\huge\bigstar\underline\mathsf{CSA:-}$

Curved surface area = πl ( R +r)

$\huge\bigstar\underline\mathsf{Frustum:-}$

Volume = (1/3) * π * h * (r12 + r22 + (r1 * r2)).

Answer 2

$\huge\star\underline\mathbb{HELLO}$

The Curved Surface Area (CSA) of the frustum of a cone is: = pi * l(R + r) where the (r) stands for = radius of the smaller circle and (R) stands for = radius of the bigger circle and the (l) = slant height of the frustum.
