A bicycle tire has a diameter of 62 \text{ cm}62 cm62, start text, space, c, m, end text. What is the distance the bicycle tire

liraira [26]

Answer:

$1,947\ cm$

Step-by-step explanation:

The correct question is

A bicycle tire has a diameter of 62 cm. What is the distance the bicycle tire travels in 10 revolutions? Round your answer to the nearest centimeter

step 1

Find the circumference of the bicycle tire

we know that

The circumference of a circle is equal to

$C=\pi D$

where

D is the diameter

we have

$D=62\ cm$

substitute

$C=\pi (62)$

$C=62\pi\ cm$

step 2

What is the distance the bicycle tire travels in 10 revolutions?

we know that

One revolution subtends a distance equal to the circumference of the bicycle tire

Multiply the circumference by 10

$(10)62\pi=620\pi\ cm$

assume

$\pi =3.14$

$620(3.14)=1,947\ cm$

Solve this k/3+4-2k=-9k

o-na [289]

K/3 + 4 -2k = -9k
First you add 9k to both sides
k/3 + 4 -2k = -9k
 +9k +9k
k/3 + 4 + 7k = 0

Now subtract 4 from both sides
k/3 + 4 + 7k = 0
 -4 -4
k/3 + 7k = -4

Now multiply 3 by both sides
k/3 + 7k = -4
x3 x3 x3
k +21k = -12

Now add k + 21k
22k = -12

Now divide both sides by 22
22k = -12
----- -----
22 22
k = -6/11
