The surface area of a ball is 3,600 square millimeters. What is the balls radius

Mathematics
1 answer:
allsm [11]4 years ago
4 0
A = 4 \pi r^2

3600 = 4\pi r^2

\dfrac{3600}{4 \pi} = r^2

r^2 = 286.479

r = 16.9

Answer: The radius is 16.9 mm.

(a) What is the difference between a sequence and a series? A series is an unordered list of numbers whereas a sequence is the s
zhenek [66]

Answer:

  • (a) A sequence is an ordered list of numbers whereas a series is the sum of a list of numbers.
  • (b) A series is divergent if the sequence of partial sums is a convergent sequence. A series is divergent if it is not convergent.

Step-by-step explanation:

A sequence is a list of ordered numbers. For example, 1, 2, 3, 4, 5.... is a sequence. The numbers are listed in a specific order when we count. In contrast, a series is the sum of the numbers in a sequence. For this multiple choice, choose the best answer that defines what a sequence is.

(a) What is the difference between a sequence and a series?

  • A series is an unordered list of numbers whereas a sequence is the sum of a list of numbers.
  • A sequence is an ordered list of numbers whereas a series is the sum of a list of numbers.
  • A series is an ordered list of numbers whereas a sequence is the sum of a list of numbers.
  • A sequence is an ordered list of numbers whereas a series is an unordered list of numbers.
  • A sequence is an unordered list of numbers whereas a series is the sum of a list of numbers.

When working with sequences and series, we look at what happens at negative and positive infinity. When a series converges, it approaches a finite number. When a series diverges, it does not approach a finite number but infinity.

(b) What is a convergent series? What is a divergent series?

  • A series is divergent if the nth term converges to zero. A series is convergent if it is not divergent.
  • A series is convergent if the nth term converges to zero. A series is divergent if it is not convergent.
  • A convergent series is a series for which lim n → ∞ an exists. A series is convergent if it is not divergent.
  • A series is convergent if the sequence of partial sums is a convergent sequence. A series is divergent if it is not convergent.
  • A series is divergent if the sequence of partial sums is a convergent sequence. A series is divergent if it is not convergent.

Hello there! :)

First, we. must make sure that variables are on the left side of the equation and numbers are on the other side.

-x=-12-11

-x=-23

x=23

Hope it helps!
