Can any one here please help me in this math problem I really need help

MArishka [77]

Answer:

The volume of the solid is the volume of the prism minus the volume of the cylinder.

For the cylinder, diameter = d = 4 cm

radius = d/2 = (4 cm)/2 = 2 cm

V = volume of prism - volume of cylinder

The volume of a prism is length times width times height.

The volume of a cylinder is pi times the square of the radius times the height.

V = LWH - (pi)r^2h

V = 6 cm * 6 cm * 15 cm - (pi)(2 cm)^2(15 cm)

V = 540 cm^3 - 60pi cm^3

V = (540 - 60pi) cm^3

Vanyuwa [196]

Answer:

1080hrs

Step-by-step explanation:

$\frac{6hr}{1day} \times5 \frac{days}{week}$

days cancel, redefine week as =5days

$\frac{30hr}{1week} \times 4 \frac{weeks}{month}$

weeks cancel redefine 4 weeks = 1 month

$\frac{120hr}{1month} \times 9 \frac{month}{1year}$

months cancel, redefine 9months= 1years

$\frac{120 \times 9}{1year}$

1080hrs per year (if I mathed 120x9 correctly that is, I didn't use a calculator so please double check that 120x9=1080)
