Answer:
Quadruple the size
Step-by-step explanation:
Explanation:
When you enlarge a linear measurement by a scale factor a the area changes by a scale factor a2
So when you double the radius. scale factor 2, the area is increased by a scale factor:
22=4
So the area is quadrupled in this case.
In the year 2008 and 2009, the company had profit 2.5 thousand dollars and 1.75 thousand dollars consecutively
In the year 2010 and 2011, the company experienced a loss of 3.3 thousand dollars and 1.4 thousand dollars.
Total profit is 2.5 + 1.75 = 4.55 thousand dollars
Total loss = 3.3 + 1.4 = 4.7 thousand dollars
Total loss is bigger than the total profit so the company needs to make profit in 2012 to break even = 4.7 - 4.55 = 0.37 thousand dollars (this is the least profit the company needs to make)
The area of a circle is:
a=πr^2 dividing both sides by π
r^2=a/π taking the square root of both sides
r=√(a/π), in this case a=44 m^2 so:
r=√(44/π) m^2
r≈14.01 m^2 (to the nearest hundredth of a square meter)
90+27=117
180-117=63
X=63 degrees
Use similar triangles (see the picture I drew at the bottom)
