Answer:
Part a) The volume of the air is 
Part b) The volume of the plastic is 
Step-by-step explanation:
we know that
The volume of the sphere is equal to

step 1
Find the volume of the complete ball (air +plastic)
we have
------> the radius is half the diameter
substitute


step 2
Find the volume of the air
we have that
The plastic is 2 mm thick
Convert to cm
2 mm=2/10=0.2 cm
so
The radius of the interior of the ball is

substitute

-----> this is the volume of the air (interior of the ball)
step 3
Find the volume of the plastic
we know that
The volume of the plastic is equal to the volume of the complete ball minus the volume of the air
so

Answer:
a1=1/2
r=3/4
n=5
Step-by-step explanation:
a1 is the first term in the geometric series
a1=1/2
r is the common ratio of the first and second term
r=(3/8)/(1/2)
r=3/4
where n is the no of the term in the geometric series
In algebra, the polynomial remainder theorem or little Bézout's theorem is an application of Euclidean division of polynomials. It expresses that the rest of the division of a polynomial by a direct polynomial is equivalent to. Specifically, is a divisor of if and just if a property known as the factor hypothesis.
The number multiplied at each stage of a geometric sequence is called its common ratio.
The volume of the cylinder would be:
282.74
Answer:
x = 44°
Step-by-step explanation:
The sum of the three angles is 180°.
So, x + x + 5 + 2x -1 = 180
4x + 4 = 180
4x = 176
x = 44°
