THIS IS MY LAST QUESTION OF MY HOMEWORK PLEASE HELP WITH THESE 2 I'LL GIVE BRAINLIEST

Step-by-step explanation:

Diameter of base of cone = 30 cm .

Hence its radius = 30/2 cm = 15 cm

So , here the figure consists of a hemisphere and a cylinder . Now , here radius of the hemisphere is 15 cm . So , height of the Cylinder = ( 85 - 15 ) cm = 70 cm

→Volume of Cylinder :-

→ Volume = π r²h

→ Volume = 22/7 * ( 15 cm)² * 70 cm

→ Volume = 49,500 cm³ .

Volume of hemisphere :-

→ Volume = ⅔ π r³

→ Volume = ⅔ * 22/7 * (15 cm)³

→ Volume = 10,607.14 cm³ ≈ 10 , 607 cm³ .

Hence Volume = ( 10 , 607 cm³ + 49,500 ) cm³ = 60,107 cm³
