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:
$h= \frac{V}{SA} = \frac{323.5}{\pi (7)^2} =2.1015~~in$

Are you satisfied?
