Answer 2

Answer:

97.17cm³

Step by step explanation:

volume of cone= πr²h/3

volume of cylinder= πr²h

volume of hemisphere= 2/3πr³

Totalvolume = volume of (cone+cylinder+hemisphere)

=>πr²h/3 + πr²h + 2/3πr³

=>πr²(h/3+h+2/3r)

=>π(3.5)²{6.5/3+6.5+2/3(3.5)}

=>22/7*35/10{65/30+65/10+2/3(35/10)}

=>11{13/6+13/2+7/3}

=>11{(13+26+14)/6}

=>11{(53/6)}

=>11*53/6

=>583/6

=>97.17 cm³
