Answer:
I'm not so sure but I know that you have to multiply all the numbers... so that should be 689.04
Step-by-step explanation:
I hope that helped
4a+2-3c+6+7c-3-3b+2a-5b you can combine 4a and 2a to get 6a
6a+2-3c+6+7c-3-3b-5b you can combine 5b and 3b to get -8b
6a+2-3c+6+7c-3-8b you can combine 3 and 2 and 6 to get 5
6a+5-3c+7c-8b you can combine 3c and 7c to get 4c
6a+5+4c-8b
Radius of the circle = sqrt((7 - 0)^2 + (0 - 0)^2) = sqrt(7^2) = 7
Equation of a circle is given by (x - a)^2 + (y - b)^2 = r^2; where (a, b) is the centre of the circle.
Required equation = (x - 0)^2 + (y - 0)^2 = 7^2
x^2 + y^2 = 49
So to solve for r, you need to isolate the variable onto 1 side. To do that, divide both sides by 2 pi, and your answer will be 
Answer:
The answer would be 6.
Step-by-step explanation:
Divide 6 by 2=3
5-3=2
2+4=6
