Answer:
(if its a true or false question) True
Step-by-step explanation:
<u>We know-</u>
<u>Area of a circle = </u>
A=(π)r2
<u>Circumference of a circle = </u>
C=2(π)r
<u>Where pi is a constant and r is the radius of the circle.</u>
<u>Using these two formulas we can express A in terms of C as follows:</u>
<u />
c2=[2(π)r]2
⇒ c2=4[(π)2]r2 ⇒ c2=4(π)[(π)r2]
As (π)r2=A ⇒c2=4(π)A
<u>Therefore:</u>
A=c2/4(π)
Here's how you do it. You'll use this forever,
so you should memorize it:
A fraction is just a short way to write a division.
Whenever you see a fraction, it means
(the top number) divided by (the bottom number).
When you actually do the division, the quotient you get
is the decimal that's equal to the fraction.
To find the decimal equivalent of a fraction, divide
the top number by the bottom number.
(6) divided by (20) = 0.3 .
sum of all sides of triangle=180°
7x+13x+16x=180°
36x=180°
x=180°/36
x=5
angle D=7x
=7(5)
D=35°
angle E=13(x)
=13(5)
E=65°
angle F=16x
=16(5)
F=80°
angle D=35°
angle E=65°
angle F=80°
D as you can see on the number line d is 1/3 of the way to -2
