Step-by-step explanation:
Here we're interested in the circumference: C = pi*d. In this case C = 3.14*(28 inches) = 88 inches.
Now divide this 88 inches into 200 feet to get the # of revolutions ncessary to travel 200 feet.
200 feet 12 in
------------ * --------- = 2400 inches
1 1 ft
2400 inches
----------------------- = 27.2 revolutions (answer)
[ 88 inches/ rev ]
Answer:
1: 5.83
2: 4.12
3: 3.61
4: 5
5: 6.32
6: 5.10
Step-by-step explanation:
The Pythagorean theorem is a^2 + b^2 = c^2
For all of these you can count the number of blocks over to find two sides of the triangle.
For example: the first one has two sides, one is 3 units, the other is 5. To find the missing angle you square 3 and 5, then add that together. That is equal to 34. 34 = c^2. To get the c by itself, you then take the square root of 34. So the missing side (c) is equal to 5.83.
3.75
10 ft - 2.5
Half of 2.5 is 1.25.
2.5 + 1.25 = 3.75
