Answer:
Volume of solid = 10,466.67 unit² (Approx)
Explanation:
Given:
Height of cylinder = 20 unit
Radius of hemisphere = 10 unit
Radius of cylinder = 10 unit
Two hemisphere = 1 sphere
Find:
Volume of solid.
Computation:
Volume of solid = Volume of cylinder + Volume of sphere
Volume of solid = πr²h + 4 /3[πr]³
Volume of solid = π[r²h + (4 /3)(r)³]
Volume of solid = 3.14[(10)²(20) + (4 /3)(10)³]
Volume of solid = 3.14[2,000 + 1333.34]
Volume of solid = 10,466.67 unit² (Approx)
