Answer:
C) 302 ft².
Step-by-step explanation:
Given : A circle with radius 14 ft and a circle with radius 10ft.
To find : what is the difference in the areas.
Solution : We have given that radius 14 ft and a circle with radius 10ft.
Area of circle = π
Area of circle 1 = π
Area of circle 1 = 196 * 3.14.
Area of circle 1 = 615.44 ft².
Area of second 2 = π
Area of circle 2 = 100 *3.14.
Area of circle 2 = 314 ft²
Difference = 615.44 - 314
Difference = 301.44 ft²
Rounded 302 ft²
Therefore, C) 302 ft².

Step-by-step explanation:
Because the length of ST is calculated using pythagorean theorem:
Where the square of the hypotenuse is equal to the sum of squares of the other two sides of a right triangle. In this case, the hypotenuse is ST and the other two sides are distances between S and T over the X and Y axis. Those are easily calculated:
Where x is the distance between S and T over X axis and Y distance over Y axis, sx and tx are X coordinates of S and T, sy and ty are Y coordinates of S and T.
Using that formula, you get that y = 17 and x = 8.
Back to the pythagorean theorem, if we put those number in the formula of the pythagorean theorem, we get something like this:
And finally, the correct answer is in fact 353.
Answer: $ 618
Step-by-step explanation:
Money borrowed = $1,854
Total months taken to repay = 18 (Number of installments)
Money paid per month =
Now , money paid in 1 year = 12 x $ 103 =$ 1236 [1 year = 12 months ]
After a year , Haley still owe = $1,854 - $ 1236= $ 618
Hence, Haley still owe her parents $618 after a year .
