Question

A conical biscuit of inner radius 3.5 cm is
0.5 cm thick and 12 cm high. Find the inner
height and volume of cream it can hold.
h = 12 cm​

Answer 1

please see the picture dear....

Answer 2

Given : In circle with centre O

CD is the diameter and AB is the chord

which is bisected by diameter at E

OA and OB are joined

To prove : ∠AOB = ∠BOA

Proof : In ∆OAE and ∆OBE

OA = OB (Radii of the circle)

OE = OE (Common)

AE = EB (Given)

∴ ∆OAE = ∆OBE (SSS criterian)

∴ ∠AOE = ∠BOE (c.p.c.t.)

Hence diameter bisect the angle subtended by the chord AB.
