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)
Answer:
Step-by-step explanation:
Slope-intercept form: y = mx + b
The line intersect Y-axis at y=0 so b = 0
The line passses through points (0, 0) and (2, -1), so the slope:
Therefore the equation:
Step-by-step explanation:
A straight line adds up to 180°
m+3m=180°
4m=180°
m=45°
3m=45°
angle CBD=3(45)
=135°
The formula for area of a circle is (pi)*radius^2
Radius is half of diameter so the radius is 2.
2 squared is 4, then multiply by pi to get an answer of 4(pi) or 12.56.
