Answer:
11.33 in. to the nearest hundredth.
Step-by-step explanation:
The perimeter of the shaded area = length of the 2 straight lines + the length of the 2 arcs = 4 + length of the 2 arcs.
Calculate the length of the outer arc:
This equals (30 / 360) * perimeter of the largest circle
= 1/12 * 2 π * 8
= 4/3 π in.
The inner circle has a radius of 8 - 2 = 6 ins
so the length of the inner arc
= 1/12 * π * 2 * 6
= π in.
So the perimeter of the shaded region = 4 + 4/3 π + π
= 4 + 7π/3
= 11.33 in.
Answer:
18/4
Step-by-step explanation: in order to get an equivalent ration just multiply both numerator and denominator by the same number
in this case I multiplied by 2 and got 18/4
The answer for this question is 6
Well I know that c. goes with I. just because I saw so many x^3 graphs.
For a. the parent function is x^2, so 0.5x^2 should look about the same as x^2, so the answer is VI.
