So we know the formula for circumference is C= πrd. And Circumference is the distance around a circle.
Example: C= circumference
C= 6.28 can u find the circles area :?
Step 1: divide 6.28 by 3.14 as the formula says.
Step 2 : after u divided u get 2 which is the diameter. and u divide the diameter by 2 because we are trying to get the radius because the formula for the circles area is
A= πr ^2
r = radius
r= 1
so what is 3.14 times 1
= 3.14
so 3.14 is the answer
I hope this helped u understand.

Answer:
(3,4) domain is 3, (1,3) domain is 1, (1,4) domain is 1, (5,2) domain is 5
Step-by-step explanation:
Domain is the input, and range is the output. Here's a detailed video you should watch

Let
h
represent hours worked.
Now, we know the pay for one hour of work is
$
9.50
. So, the amount of pay for
h
hours worked is given by
9.50
h
.
Furthermore, since we're saving for a camera that costs
$
247
,
we want at LEAST
$
247
(but it's okay if we have more). So, we'll be using
≥
in the inequality.
So, our inequality is
9.50
h
≥
247
To solve, we simply divide both sides by
9.50
:
h
≥
247
9.50
h
≥
26
You need to work at least
26
hours to buy the digital
Answer:
23ft approx
Step-by-step explanation:
Given data
Distance from tree= 10ft
Length of ladder= 25ft
We can find the height of the tree by applying the Pythagoras theorem
z^2= x^2+y^2
z= The height of the ladder
x= The distance from the tree
y= The height of the tree
25^2= 10^2+ y^2
625=100+y^2
625-100=y^2
525=y^2
y= √525
y= 22.91
Hence the height of the tree is 23ft approx
