There's no such factors that will evenly divide into 86 ao ther for 86 is a improper number when it comes to product .
- Hopee this helps u in anyway .
Answer:
39.27
Step-by-step explanation:
The area of a semi-circle is pi times the radius squared divided by 2. So basically standard area of a circle formula (pi times the radius squared) but then you add in the extra step of dividing it by 2.
The formula looks like this:
π × r² ÷ 2
The radius is half the diameter of the circle. So basically think of it as a line to the middle of the circle. Our diameter is 10, (the diameter is the entire length of the circle. It gives us this already. If you need diameter and only have the radius add the radius together twice or multiply it by 2 to get the diameter. Fun fact..?)
and it tells us to substitute pi for 3.142.
So, plugging our numbers in we get:
3.142 x 5^2 ÷ 2 = 39.275.
Cut out the 3rd decimal place (5) as it tells us to only include the first 2 decimal places, and we finally end up with 39.27.

Answer:
C = 2
Step-by-step explanation:
9c + 14 = 2c^2 + 9c + 6
-9c -9c
14 = 2c² + 6
-6 -6
8 = 2c²
4 = c²
c = 2
Well.. what is it can you put up a pic of it
It is already in it simplest form, you can’t square root the (4k-8) and -3 you can’t lower anymore
