Answer:
c) 2 pi x
Step-by-step explanation:
The circumference is based on the equations:
C = pi * d where d = diameter
We also know that the radius is half of the diameter as its the length of a line from the centre of the circle while the diameter is the length of two opposite points through the centre of the circle.
This tells us that d = 2r
So we can replace the equation for the circumference with:
C = pi * 2r
An increase of x to the radius would thus mean that the circumference is increased by 2(pi * x), as 2(pi * (r + x) could be used to find the new value of the circumference, which is the same as:
2(pi * r) + 2(pi * x)
So the answer is 2 pi x
Answer:
x = 37
Step-by-step explanation:
<u>Step 1: Subtract 5 from both sides</u>
x + 5 - 5 = 42 - 5
x = 37
Answer: x = 37
Answer:
the answer is 5.8
Step-by-step explanation:
divide numerator (8) by the denominator (10):
8 / 10 = 0.8
add this value to the integer part: 5 + 0.8 =
5.8 So,
5 8/10 = 5.8
Geometric sequences are mostly found in Book IX of Elements by Euclid in 300 B.C. Euclid of Alexandria, a Greek mathematician also considered the "Father of Geometry" was the main contributor of this theory. Geometric sequences and series are one of the easiest examples of infinite series with finite sums. Geometric sequences and series have played an important role in the early development of calculus, and have continued to be a main case of study in convergence of series. Geometric sequences and series are used a lot in mathematics, and they are very important in physics, engineering, biology, economics, computer science, queuing theory, and finance.<span> It was included in Euclid's book </span>Elements<span> that was part of a composition of other math theories for people that became very popular because it was the first collection that showed alot of the main math theories together featured simply.</span>
