The diameter of a sphere is 4 centimeters.
ELEN [110]
The volume of a sphere refers to the number of cubic units that will exactly fill a sphere. The volume of a sphere can be found or calculate by using the formula V=4/3πr^3, where r represents the radius of the figure.

In this exercise is given that a sphere has a radius of 4 centimeters and it is asked to find its volume and use 3.14 as the value of π or pi. The first step would be substitute the values into the previous mention formula.

V=4/3πr^3
V=4/3(3.14)(4 cm)^3
V=4/3)(3.14)(64 cm^3)
V=267.9 cm^3
The volume of the sphere is 267.9 cubic centimeters.

Suppose John has a torn tendon and is facing surgery to repair it. The surgeon explains the risks to John: infection occurs in 2
serg [7]

Answer:

Step-by-step explanation:

The total number of operations prepared by the surgeon is X.

The questions can be solved by set

For two sets A and B,

Where A= The surgery done with infections

B= Surgery done which failed

n(AᴜB) is the number of elements present in either of the sets A or B.

n(A∩B) is the number of elements present in both the sets A and B.

Y= number of surgery  which succeed and are free from infection

n(AᴜB) = n(A) + (n(B) – n(A∩B) + Y

X= 2% of X + 12% of X -1.35% of x + Y

X=0.02X+0.12X-0.0135X+Y

X=0.1265X+Y

Y=X-0.1265X

Y=0.8735X

Therefore the operation s that succeed and are free from infections  is 0.8735 or 87.35%
