The correct answer is - B. 5.24 lb.
Explanation:
Given is a bowling ball, so it is a sphere.
The radius is given as = 5 inches
Volume of the sphere =
Putting r=5 and pi = 3.142 in the above formula, we get
volume = 523.66 cubic inches
Also given is - one cubic inch weighs 1/100th of a pound
So, 523.66 cubic inches will weigh =
Hence rounding this off we get the weight of the bowling ball as 5.24 lb.

Answer:
√145 ≈ 12.04
Step-by-step explanation:
The length of the space diagonal is the root of the sum of the squares of the prism edge lengths:
d² = a² +b² +c² = 6² +3² +10² = 145
d = √145 ≈ 12.04 . . . inches
__
The face diagonal is found using the Pythagorean theorem in the usual way:
f² = a² + b²
The space diagonal is the hypotenuse of the right triangle whose sides are the face diagonal and the remaining edge:
d² = f² +c²
d² = a² +b² +c²
__
Here is a diagram.
Answer:
μv =
σv=
Step-by-step explanation:
Volume is found by multiplying the area and height. Since we're given both area and height of 10 and 5 cm respectively then
μv =A.h= 10*5= 50 cm^{3}
The standard deviation of the volume will be
σv= 0.3*10=
