11: To add 3/8 and 2/5 you need to find the least common denominator (in this case 40), and change both fractions by multiplying to get the least common denominator and add them together

2/8 = 10/40
2/5 = 16/40
16/40 + 10/40 = 26/40 = 13/20

12 a: 5/6 = 45/54
4/9 = 24/54
45/54 - 24/54 =21/54

b: 7/10 = 56/80
3/8 = 30/80
56/80 = 30/80 = 26/80 = 13/40

The area of the circle shown below is 100π. What is the diameter (D) of the circle?

Phoenix [80]

$\bf \textit{area of a circle}\\\\
A=\pi r^2~~
\begin{cases}
r=radius\\
-----\\
A=100\pi 
\end{cases}\implies 100\pi =\pi r^2
\\\\\\
\cfrac{100\pi }{\pi }=r^2\implies 100=r^2\implies \sqrt{100}=r\implies \boxed{10=r}$

since a diameter is twice as long as the radius, this one is also 2r.
