Answer:

Step-by-step explanation:

Use the formula for radius and circle circumference.

$d=2r \\ \\ C=2\pi r$

Since we know the diameter, if we divide that by 2, we can get the radius.

$29.5/2=14.75$

Now we can plug that value into the circumference formula to get the circumference.

$C=2(14.75)\pi \\ \\ C=29.5\pi \\ \\ C=93$

*Since we're rounding to the nearest inch.

n200080 [17]

The response is
x greater than or equal to -9
proof
8x - (5x + 4)>= -31, 3x- 4>= -31, 3x >= -27, x>= -27/3= -9

Two cars start from the same point driving in opposite directions. Both cars drive 6miles. One car stops, the other car makes a

Answer:

14.4 mile²

Explanation:

1. By driving 6 miles each, the cars will be 6 miles + 6 miles = 12 miles appart.

2. When one car stops and the other car makes a 90° left-hand turn and drive 8 miles, you can model the situation with a right triangle, where one leg is 12 miles, the other leg is 8 miles, and the hypotenuse is the distance that separates the cars.

Hence, you must use Pythagoras to find that distance.
