Question

What is the formula of the total surface area of a frusttum come with top and bottom tadii 16 and 12 cm

Answer 1

Hello Raghunath !

Answer:

Formulae :

LSA of a Frustum = πs(r + R)

TSA of a Frustum = π[(r + R)s + (r² + R²)]

Volume of a Frustum = (1/3)πh[R² + Rr + r²]

Where s = $\sqrt{(R - r)^{2}+ h^{2}}$ and r < R

We can't solve this problem, As sufficient data is not provided.

Thanks !
