Answer:

x=5

Step-by-step explanation:

We know that corresponding sides will have the same angles. In this case it's 12 and 12+3=15. That means that larger triangle is 15/12=5/4=1.25 times larger.

So we apply that for 3x+1 as well.

1.25(3x+1)=4x

3.75x+1.25=4x

.25x=1.25

x=5

The diameter of a pizza is 14 inches. what is the circumference?

algol13

The formula for finding the circumference of a circle is 2πr or πd
So, there are 2 ways to find it.

1) Using the diameter, you would do π x 14.
This will give you 43.9822971503
(round the number to however many dp it says to do :) )

2) Using the radius (half of the diameter), you could do 2π x 7
which will also get you 43.9822971503
