Answer:
circumference - diameter
circumference - 2 times radius
area - radius squared
Step-by-step explanation:
we know that
<u><em>The circumference of a circle is equal to</em></u>
or 
where
D is the diameter and r is the radius
therefore
or 
The number pi is the ratio circumference - diameter or is the ratio circumference - 2 times radius
<u><em>The area of the circle is equal to</em></u>
therefore
The number pi is the ratio Area - radius squared
Answer:
The slope of this line would be 3.
Step-by-step explanation:
To find the slope of any line, use the slope formula and the points given.
m(slope) = (y2 - y1)/(x2 - x1)
m = (4 - 1)/(3 - 2)
m = 3/1
m = 3
Step-by-step explanation:
solve the equation with formula : SOH, CAH,TOA.
from the above, SOH is to be used to answer the question.
so, Sin∆=Opp/Hyp
∆=41°
Opposite=AB
Hyp= 13.5cm
sin 41°=AB/13.5
sin41°=0.6560
0.6560= AB/13.5
AB=13.5*0.6560
AB=8.856cm
to three significant figure AB=8.86 cm approximately
Answer:
<h2>x > -5</h2>
Step-by-step explanation:
-5(x + 7) < -10 <em>use the distributive property </em><em>a(b + c) = ab + ac</em>
(-5)(x) + (-5)(7) < -10
-5x - 35 < -10 <em>add 35 to both sides</em>
-5x < 25 <em>change the signs</em>
5x > - 25 <em>divide both sides by 5</em>
x > -5
Answer:
X= z/3 - y/3
