Question

More math help please!

Answer 1

1)V=πR².H==> 323.5 x πx7²xh==>323.5=49π.h


h=323.5/49π==> h=2.101 in


2) Horizontal rectangular prisma: V₁=3x8x5 = 120 cm³
Vertical rectangular prisma : V₂=2x5x6 = 60 cm³
TOTAL VOLUME =V₁+V₂ =120+60=180 cm³

Answer 2

AS we know that:


`V=SA*h`

And we have the volume and we can calculate the SA,,,

So that, we can conclude:

`h= (V)/(SA) = (323.5)/(\pi (7)^2) =2.1015~~in`

Are you satisfied?
