Answer:
310.23
Step-by-step explanation:
circumference is radius * 2
to get radius from circumference, divide circumference by 2
18.84 / 2 =9.42
area for circle:
pi * r^2
3.14 * 9.94^2
3.14 * 98.8
310.23
Answer:
The y intercept is (0,5)
Step-by-step explanation:
f(x) = 5 * (1/6)^x
What is the y intercept? Let x = 0
f(0) = 5 * (1/6)^0
f(0) = 5*1 = 0
The y intercept is (0,5)
Answer:
I think it should be 
Step-by-step explanation:
When the question said area of the cube, I think it was supposed to be surface area, which would 
where a is the length of one edge. Given that the length of one edge is 2x, we would plug in 2x to the equation to get
which would become .
