Answer:
11550cm³
Step-by-step explanation:
Hemisphere
r= 15cm (radius of cone is same as radius of hemisphere)
Cone
r= 15cm
h= 55-15 = 40cm
Volume of solid= V of cone + V of hemisphere
= 1/3πr²h + 2/3πr³
= 1/3πr²(h+2r)
= 1/3 x 22/7 x 15²(40+2 x 15)
=22/7 x 5 x 15 (40 + 30)
= 22/7 x 5 x15x 70
=22 x 5 x 15 x 10
Volume of solid = 11550cm³
