Surface area = 4 pi r^2
where
pi : 3.14 a constant
r : raduis
surface area is the change of volume with respect to raduis
volume = 4/3 pi r^3
dvolume/dr = 4 pi r^2
you can prove the identity with double integration in spherical coordinates or volumes of revolutions and polar coordinates
The answer i D because 11-6=5
Answer:
39/56
Step-by-step explanation:
Answer:
68.04 cm^3
Step-by-step explanation:
The volume of the prism is given by
V = Bh
where B is the area of the base and h is the height
B - area of the triangle
B = 1/2 bh = 1/2 (5.4) (3.6) = 9.72
The volume is
V = 9.72*7
68.04 cm^3
