let's find the area of the outer circle and the inside circle
the inside's circle area
A= π x 6²=36π
the outer's
A' = π x 4x²= 4πx²
A'-A=4πx²- 36π=160πcm² equivalent to x²- 9=40, so x²=49 implies x =sqrt(49)=7, x=7.
when you divide 2 fractions, you reverse the second fraction then use multiplication
3/5 divided by 3/15 becomes
3/5 x 15/3 = 45/15 = 3
-2/3 - 5/6
We need common denominators so, since 3 can go into 6, we only need to multiply the first fraction by 2.
= -2 x 2 / 3x2 - 5/6
= -4 / 6 - 5/6
We only subtract the numbers that are in the numerators,
= -4-5 / 6
= -9/6
Both nine and six are divisible by 3, so to put into lowest terms...
=-9÷3 / 6÷3
= -3/2 <--- Final Answer
Answer:
0.9412
Step-by-step explanation:
Ultimately, if you know the length of the arc, and you know the length of the radius, the central angle (in radians) is just how many radii long the arc is. angle=arc lengthradius length=16 feet17 feet≈0.9412.
Median is the middle number so it would be 250
