The diameter is 20 so the radius is 10.
A=<span>πr^2
A=</span>π10^2
A=100π
C=2πr
C=2π10
C=20π
Answer:
1.) 1/2x
2.) 3a
3.) <10
4.) 8/p
5.) =0
6.) =0.25
7.) x-6=4.5
8.) y/8=3.2
Step-by-step explanation:
For #1 all you have to do is add them together. For #2 it is the same thing. For #3 all you need to do is use the less then (<) symbol with a 10 behind it. For #4 quotient means to divide so all you need to do is put a division symbol between the two factors. For #5 all you have to do is substitute 1.5 for the letter A and subtract them. For #6 all the do is substitute 2.25 for b because you convert the fraction to a decimal which is 25/100 which equals .25 then you divide the two numbers. For #7 the difference mean to subtract so you put x-6 instead of the difference between x and 6, then it equals 4.5 because you convert the fraction which would be 50/100 which equals .50. For #8 all you do is flip the word quotient the a division symbol because quotient means to divide.
If you just factor the original polynomial(The area) then you will find that one of the factors is c-2(the length) and the other will be the width.
When I factored it, I got 2c+3 as the width.

Here is the solution of the given problem above.
Firstly, to make the solution easier, let us convert the mixed fractions.
2 3/4 is 11/4 (Pounds of beef needed)
1 1/6 is 7/6 (Pounds of beef available)
So, to get how much more he needs, we will deduct 7/6 from 11/4 and we get 19/12. And this fraction is equivalent to option A. 1 7/12. Therefore, he needs 1 7/12 pounds more. hope this answer helps.
Where is the grid are u gonna take a pic?
