Answer C
Circle area = pi * r^2
If the area is 36*pi, then r^2 is 36 and r (the radius) is 6.
The perimeter of one of the regions consists of two radiuses and an eighth of the circle's circumference.
Two radiuses=6*2=12
An eighth of the circumference: (2*pi*r)/8 = 2*pi*6/8 = 2*6/8*pi = 1.5*pi
So, the perimeter of a section is 12 + 1.5pi

Mai and Tyler work on the equation 2/5b+1=-11 together. Mais soulution is b=-25 and Tyler’s is b=-28. Here is their work. Do you

Anika [276]

Answer:

No I don't agree with their solution; both their answers are wrong.

Correct answer is $b=-30$ .

Step-by-step explanation:

Given:

$\frac{2}{5}b+1=-11$

Now given:

According to Mai $b = -25$ and According to Tyler $b = -28$

Now we need to find which of them is correct.

So we will solve the given equation we get;

$\frac{2}{5}b+1=-11$

Subtracting both side by 1 we get;

$\frac{2}{5}b+1-1=-11-1\\\\\frac{2}{5}b =-12$

Now Multiplying both side $\frac{5}{2}$ we get;

$\frac{2}{5}b\times\frac{5}{2}= -12 \times \frac{5}{2}\\\\b=-6\times 5\\\\b=-30$

Hence both of them are incorrect, correct answer is $b=-30$ .
