Answer:
7
Step-by-step explanation:
7.base of triangle=√(32.5²-28²)
=√4.5(32.5+28)
=√4.5(60.5)
=√272.25
=16.5
area of triangle=1/2 ×16.5×28
=231
volume=231×31=7161 km³
8.
39.4-25=14.4
width=√(30.6²-14.4²)
=√16.2(30.6+14.4)
=√16.2(45)
=√729
=27
volume=(25+39.4)/2 ×27×35
=(64.4)/2×27×35
=32.2×27×35
=30429 cm³
H^2=p^2+b^2
