Question

a right cirular cone of height 4cm has a curved surface area 41.7 cm2. Find the volume of the cone.
​

Answer 1

Step-by-step explanation:

V≈17.35cm³

h =Height =4cm

A = Surface area

41.7 cm²

Using the formulas

A=πrl+πr2

AB=πr2

V=ABh

3

l=r2+h2

Solving for V,

V=A2h/3(πh2+2A)=41.72·4

3·(π·42+2·41.7)

≈17.34569cm³

hope it helps!!
