Radius of the inner circle = 13.2 ÷ 2 = 6.6 mm
Area of the inner circle = π (6.6)² = 43.45π mm²
Radius of the larger circle = 6.6 + 4.4 = 11mm
Area of the larger cicle = π(11)² = 121π mm²
Area of the washer = 121π - 43.45π = 243.3 mm²
Answer: 243.3 mm²
Answer:
Step-by-step explanation:
For a function to have a y-intercept of -1, means that
when x = 0, f(0) = -1.
we must look for which of the options meets this condition.
I will number the options as follows:
when x = 0:
Note: , so
function 1 meets the condition for the y-intercept.
when x = 0
function 2 also meets the condition for the y-intercept.
when x = 0
Note:
function 3 also meets the condition for the y-intercept.
when x = 0
function 4 does not meet the condition for the y-intercept, so we discard it.
We are left with the 3 first functions as options. Now we consiser that the amplited must be 2.
The amplitude in an oscillatory function like these is the number that accompanies the sine or the cosine:
f(x) = ±Asin(x) or
f(x) = ±Acos(x)
so out of the option we have to consider, only the second function has a number 2 next to the sine function:
this function will have a y-intercept of -1 and an amplitude of 2 (because the sine has a number 2 next to it)

Answer:
5/6
Step-by-step explanation:
2 1/2 -> 5/2
5/2 divided by 3, which is 0.83333333333
0.83333333333 as a simplied fraction is 5/6
