The distance around a round object (i.e. a circular pool, in this case) is also known as its circumference.
The formula for working out circumference is π × d, where π is the value of pi (usually rounded to 3.14) and d is the diameter.
Therefore, to work out the diameter, you just have to work backwards.
So you know the circumference, and you know the value of pi, therefore you just do:
C = π × d
67.51 = 3.14 × d
Now you just have to divide both sides by 3.14 to isolate the value of d and work out the diameter:
67.51 ÷ 3.14 = d
21.5 = d
Therefore, the diameter is 21.5 ft.
Answer:
um whats the question
Step-by-step explanation:
Answer:
3 beverages, 5 appetizers, 8 entrees, and 4 desserts.
Step-by-step explanation:
I think you meant 20 items, so let's do that. To find 15% of 20, we multiply 20 by .15. This gets us 3. We repeat this with all the other numbers, using different decimals, of course. We get 3 beverages, 5 appetizers, 8 entrees, and 4 desserts. 3 + 5 + 8 + 4 is 20, so everything checks out.
Answer:
A. Yes (True) B. Yes (True)
Step-by-step explanation:
The first some is true because the square root of 50 is between 6 and 7, which IS greater than 5
The second one is false because the square root of 3 is between 1 and 2, which which could be some of the a+v side of the triangle.
Hope this helped
