Circumference of circle=<span>2πr</span>

Where <span>r=radius</span>

<span>2r=d</span>

<span>d=diameter</span>

So,<span>2πr=πd</span>

Note,<span>π=<span>227</span></span>

In this statement,<span>c=ci</span><span>rcumference</span>

<span>→c=πd</span>

<span>→c=π<span>(30)</span></span>

<span>→c=π30=<span>227</span><span>(30)</span></span>

<span>→c=<span>6607</span>=94.28...</span>

Circumference is <span>94.28...cm<span>s</span></span>

What is the equation of the line that passes through (1, 2) and is parallel to the line whose equation is 2x + y - 1=0?​
elixir [45]

Answer:

y=-2x+4

Step-by-step explanation:

2x+y-1=0

2x+y=0+1

2x+y=1

y=1-2x

y=-2x+1

y=mx+b where m=slope and b=y-intercept

parallel means same slope,

so the slope would still be -2.

--------------

y-y1=m(x-x1)

y-2=-2(x-1)

y=-2x+2+2

y=-2x+4

What is the 24th term if the arithmetic sequence where a1 = 8 and a9 = 56
AnnyKZ [126]

Answer:

a_{24} = 146

Step-by-step explanation:

a1 = 8

a9 = 56

Using formula for finding nth term of arithmeric sequence

a_{n} =a_{1} + (n-1)d

We have to find 24th term, therefore n = 24

a_{1} is the first term but we are missing d

d is the difference between the two consecutive terms, lets calculate it first


a9 = 56

Using the above given formula for finding d

put n = 9,  a9= 56

a_{9} =a_{1}+ (9-1)d

56 = 8 + 8d

8d = 48

d = 6


Getting back to main part of finding 24th term

n = 24, d = 6, a1 = 8

put values in nth term formula

a_{n} =a_{1}+ (n-1)d

a_{24} = 8 + (24-1)6

a_{24} = 8 + 138

a_{24} = 146
