3 0

Multiply the numerator and denominator by 4+5i
=[(2+3i)(4+5i)]/[(4-5i)(4+5i)]
=[(8-15)+(12+10)i] / [16+25] = [ -7 + 22i ] / [41]
= (-7/41) + (22/41)i

Find the volume of the solid. Round your answer to the nearest tenth

insens350 [35]

Answer:

Solution given:

Volume of cone=⅓πr²h

Volume of cylinder=πr²h

volume =πr²h=π*(10/2)²*6=471.23mm³

Volume =πr²h=π*8*12.5=314.16in³

volume =⅓πr²h=⅓*π*4²*3=50.26cm³

Volume =⅓πr²h=⅓*π*(8/2)²*12=201.06in³
