Answer 2

Volume of the come

trh

Given

h 21 cm

slant height 1 28 cm

Height of cone h 21 cm

Let radius of cone = r cm

1 28 cm

We know that

=h2 + p2

282 = 212 + 2

282 212 = r2

r 2282212

r 228212821

r2 = (7) (49)r=V749)

r =.

r 77cm

So,

Volume of the come

Tr2h

x7 7x 7 7x 21 cm

= 22 x 777 X 7 17 cm

22 x 7 x 7 x (V7)2 cm3

22 x 7 X 7 x 7 cm

= 7546 cm3
