The circumference of a circular clock is 31.4 inches.What is the diameter of the clock

Answers

Answer 1

Answer: Circumference of a circle=πd
d=diameter
Circumference=31.4 in
π=3.141592654...

31.4 in=πd
d=3.14 in / π=0.999493...in≈1 in

Answer: diameter=1 in

Answer 2

Answer: The circumference formula is
C = $2 \pi$ r

We know the circumference, so lets find the radius and we will get the diameter.

31.4 = 2 $\pi r$
divide by 2 $\pi$ to isolate r

$(31.4)/(2 \pi )$ = $(2 \pi r)/(2 \pi )$
2 $\pi$ and 2 $\pi$ cancels out.

0.4997 = r
0.5 in ≈ r (approximately)

Diameter is 2 × radius
2 × 0.5
1 in

Find the mean of 11,-7,-14,10,-5

Answers

The mean to your question is -1. What you do is: 1) add all numbers together. 2) divide the sum by the amount of numbers in the question which is 5. 3) you get -1 as your mean. Hope this helps!

Final answer:

The mean of the numbers 11,-7,-14,10,-5 is found by adding all the numbers together, and then dividing by the number of numbers. In this case, the mean is -1.

Explanation:

To find the mean of the numbers 11,-7,-14,10,-5, you'll want to add all of these numbers together then divide by the amount of numbers there are. This is because the mean is the average value of a set of numbers.

First, add up all your numbers: 11 + -7 + -14 + 10 + -5, which totals to -5. There are 5 numbers in the set, so to find the mean, you then divide -5 by 5, which equals -1. So, the mean of the set of numbers 11, -7, -14, 10, -5 is -1.
