Answer: 160 degrees
Step-by-step explanation:
(18-2)180 = 2880
2880/18 = 160
Answer: Commutative
Step-by-step explanation:
Answer: Inner Circle Circumference = 27.018 feet
Outer Circle Circumference ≈ 49.637 feet
Step-by-step explanation: You can use the formula for the circumference of a circle (πd). From here, we can plug 8.6 feet for the inner circle's diameter into the formula. C ≈ 27.018 ft for the inner circle.
Diameters work in any way no matter how you turn the line, as long as the line touches both ends of the circle. Now imagine the 8.6 feet diameter lined up with the 3.6 feet given line. You have a total of 12.2 feet, but this is not the diameter. Since this is a circle, it is safe to assume the 3.6 feet line can be rotated between the inner circle and the border of the outer circle and remain the same length. Therefore, the other end is also 3.6 feet. Totaling up the diameter to 15.8 feet. Now plug this into the formula. C ≈ 49.637 feet of the outer circle.
Answer:
The answer is: 4,500,000 kilometers or in scientific notation: 4.5 x 10^6 kilometers.
Step-by-step explanation:
Multiply to get the answer:
300,000 * 15 =
4,500,000 km
In scientific notation: 4.5 x 10^6
Answer:
First pair: -4 and 8
Second pair: -2 and 6
Third pair: -1 and 5
Step-by-step explanation:
-4 + 8 = 4
-2 + 6 = 4
-1 + 5 = 4
