Question

Finding the volume of a cone?

Answer 1

V = ⅓BH

Answer 2

v= 1/3 pi r^2 h

Answer 3

Well that's for a circle you have to find the SA

Answer 4

The base is already split into 3 parts which have easy areas to find:
a 6cm×4cm rectangle, and 2 3cm×4cm triangles

Answer 5

so would the volume be 32 cm?

Answer 6

The base area = 6×4 + 2(½×3×4) = 36cm²
The height is 8 cm.
The volume is ⅓ Base × height
=⅓×36×8
=12×8
= 96 cm³
