Answer:

52%

Step-by-step explanation:

First we have to find the total:

5 + 8 + 12= 25

Now we have to add how many red and how many blue marbles.

5 + 8 = 13.

Now you can tell that 13 > 12 so we can predict that the answer is 52%

However, lets go ahead and divide 13 from 25

13/25 = .52

This means that the answer is 52%!

What is the area of a circle. Using 3.14 for. A circle with diameter of 8.4 ft.
ira [324]

Hey there! I'm happy to help!

First, let's find the radius. The radius is half of the diameter.

8.4/2=4.2

Here's how to find the area of a circle.

Square the radius.

4.2²=17.64

And multiply by pi (3.14 in our case)

17.64(3.14)=55.3896

We round to the nearest tenth, giving us an area of 55.4 ft²

Have a wonderful day! :D

Step-by-step explanation:

add up all the inside angels, you'll get 122, subtract that from the total area of the triangle which is 180. you will have 58 for your missong inside triangle. the outside line makes 180 with the angel we just found, so subtract 58 from 180 and you get 122. check out Khan Academy for help.
