a.) the volume = volume of cone + volume of hemisphere
Therefore (1/3pier²h) + (2/3pier3)
=( 1/3*22/7*35/10*35/10*123/10)+(2/3*22/7*35/10 *35/10 *35/10)
=157.85cm + 89.83= 247.68
B.) volume = 2/3*22 /7 * 10 *10 *10 +2/3 *22/7 * 3 *3*3
=2095.23+ 56.57
=2151.8
Therefore (1/3pier²h) + (2/3pier3)
=( 1/3*22/7*35/10*35/10*123/10)+(2/3*22/7*35/10 *35/10 *35/10)
=157.85cm + 89.83= 247.68
B.) volume = 2/3*22 /7 * 10 *10 *10 +2/3 *22/7 * 3 *3*3
=2095.23+ 56.57
=2151.8
