Answer:
36pi
Step-by-step explanation:
Since the formula for the circumference is C=2*pi*r
12pi=2*pi*r we can divide and get r=6 cm
Then, we can use the formula for the area of a circle: Area=pi*r^2 and get Area=pi*6^2=36*pi.
Note: the negative on question 13 becomes a positive as the negative is getting multiplied by itself (another negative) so it becomes a positive
Answer:3x-4y
Step-by-step explanation:
To express the sum of (2x-5y) and (x+y),
We are going to have
2x-5y+x+y
The next thing to do is to collect the like terms;
Then we have;
2x+x-5y+y
Answer realized will now be
3x-4y
