Answer:
(294π +448) cm³ ≈ 1371.6 cm³
Step-by-step explanation:
The half-cylinder at the right end has a radius of 7 cm, as does the one on top. Together, the total length of these half-cylinders is 8 cm + 4cm = 12 cm. That is equivalent in volume to a whole cylinder of radius 7 cm that is 6 cm long.
The cylinder volume is ...
V = πr²h = π(7 cm)²(6 cm) = 294π cm³
__
The cuboid underlying the top half-cylinder has dimensions 4 cm by 8 cm by 14 cm (twice the radius). So, its volume is ...
V = LWH = (4 cm)(8 cm)(14 cm) = 448 cm³
Then the total volume of the composite figure is ...
(294π +448) cm³ ≈ 1371.6 cm³

Answer:
U = tantheta - KX/mgcostheta
Step-by-step explanation:
The formula for calculating the coefficient is given by.
KX = mgsintheta - mgucostheta
Making u subject of the formula we have
U = tantheta - KX/mgcostheta
K = 165N/m
X = 12 cm = 0.12m
U = tantheta - 165*0.12/mg*costheta
The question isn't complete but with this you can fix value for the mass and angle to get the final answer easily
