Suppose the circumference of a circle is six pi what is its diameter❓

Mathematics
1 answer:
CaHeK987 [17]3 years ago
8 0

Answer:

Step-by-step explanation:

Circumference = 2×pi×radius

6pi=2×pi×radius

6pi/pi=2radius

2radius=6

Since 2radius=diameter

Therefore diameter=6 units

Find the distance around one-fifth of a circle with diameter of 14 inches
Step2247 [10]

To solve this problem, you will need to know the formula to find the circumference of a circle given the diameter of a circle. After calculating the circumference, you will then divide this result by 5 to obtain the final answer needed for this problem.

<h3>Find the Circumference</h3>

The circumference of a circle is found using the formula C = 2πr.

C = 2\pi r

We are given the diameter. The radius can be found using r = D/2.

\displaystyle r=\frac{D}{2}

\displaystyle r=\frac{14}{2}

r=7

Plug in the radius to the formula for a circle's circumference: C = 2πr.

C = 2 \pi (7)

Rearrange the equation to distribute the 7 into the 2π.

C = 7(2\pi)

Distribute the 7.

C=14\pi

<h3>Find One-Fifth of the Distance</h3>

To find one-fifth of the distance (formally termed the circumference) around the circle, divide the circumference by 5.

\displaystyle \frac{14\pi}{5}

If you are looking for a simplified answer in terms of π, this will suffice. If you need an exact answer that does not reference π, continue reading.

For a solution not in terms of π, first, multiply 14 by π.

14\times\pi = 43.98229715

Divide this value by 5.

\displaystyle \frac{43.98229715}{5} = 8.7964594

To make this easier to present, round to the hundredths place.

8.7964594 \approx 8.80

The final answer, dependent on the value you are asked to provide, is:

{\boxed{\displaystyle \frac{14\pi}{5} \ \text{inches}}

\boxed{\text{approximately} \ 8.8 \ \text{inches}}

Which list is in order from least to greatest? 1.94 x 10 1.25x 10.6x109.8.1 x 10 O 1.25x 10-2 194 10*6x10* 8.1 x 10 O 1.25x 10-2
pickupchik [31]

Answer:

(a)\ 1.94 * 10 ^{-5},\ \ 1.25 *10 ^{-2},\ \ 6 *10 ^{4},\ \ 8.1 *10^{4}

Step-by-step explanation:

Given

(a)\ 1.94 * 10 ^{-5},\ \ 1.25 *10 ^{-2},\ \ 6 *10 ^{4},\ \ 8.1 *10^{4}

(b)\ 1.94 * 10 ^{-5},\ \ 6 * 10^4, \ \ 8.1 *10^{4},\ \ 1.25 *10 ^{-2}

(c)\ 1.94 * 10 ^{-5}, \ \ 8.1 *10^{4},\ \ 6 * 10^4,\ \ 1.25 *10 ^{-2}

(d)\ 1.94 * 10 ^{-5},\ \ 1.25 *10 ^{-2},  \ \ 8.1 *10^{4},\ \ 6 * 10^4

Required

Which list is in ascending order

To do this, we analyze each of the options 1 after the other.

(a)\ 1.94 * 10 ^{-5},\ \ 1.25 *10 ^{-2},\ \ 6 *10 ^{4},\ \ 8.1 *10^{4}

Convert each list item to decimal

1.94 * 10 ^-5 = 0.0000194

1.25 *10 ^-2 = 0.0125

6 *10^{4} = 60000

8.1 *10^{4} = 81000

The list is in ascending order because:

0.0000194 < 0.0125 < 60000 < 81000

<em>No need to test other options</em>
