Answer: 2/3 or 1/3

Step-by-step explanation: If we have a cake that has a total of 12 pieces, and we gave four to someone else we would have 8/12 pieces left. Now if we simplify then we would have 2/3 left.

Alternate explanation: Now if we just want to divide 4/12 then we would have 1/3.

I'm happy to help let me know if I'm wrong!

Answer:

ASA

Step-by-step explanation:

We can see that the triangle has at least one similar side and one similar angle. We can also see that the triangles meet at a point, so they must have the same angle at that point where they connect. So that leads us to our answer being ASA since they have two similar angles and one similar side. This is the answer that I think is correct just by looking at the image. I haven't take this class since last year, so this is simply from memory. Correct me if I am wrong!

Answer:

The formula for the area is πr² where r is the radius.

But the radius wasn't given so we have to ring it via the circumference given.

Step-by-step explanation:

Circumference = 87.92

To find the radius;

The formula for finding the circumference is 2πr. Therefore;

$87.92 = 2\pi r \\ \pi = 3.14 \\ therefore \\ 87.92 = 2 \times 3.14r \\87.92 = 6.28r \\ we \: have \: to \: make \: r \: the \: subject \\ r = \frac{87.92}{6.28} \\ = 14$

So now that we have our radius to be 14 we substitute it into the equation for finding the area

$area = \pi {r}^{2} \\ r = 14 \\ therefore \\ area = 3.14 \times {14}^{2} \\ = 3.14 \times 196 \\ = 615.44 \: square \: inches$
