Answer 2

Step-by-step explanation:

diameter of cone = 42cm(radius (r)= 42cm/2=21cm)

slant height of cone(l) =29cm

height of cone =?

(l)2=(h)2+(r)2

(29)2=(h)2+(21)2

841cm=(h)2+441cm

841cm-441cm=(h)2

(h)2=400cm2

h=under root 400cm2

h= 20cm

Volume of conical vessel = ⅓ πr2h

=_1_×_22_×21cm×21cm×20cm

3 7

=22×7cm×3cm×20cm

=154cm×60cm2

=9240cm3
