Answer:
233.53 s
Step-by-step explanation:
The sum of best times for the legs is ...
56.81 +59.22 +57.39 +60.11 = 233.53 . . . seconds
Without additional information about the effects of training or the normal variation in times, this is the best prediction we can make.
You wouldn’t because 3 is the base number and cannot be simplified anymore
if other experts state the same thing in their own paper or document.
Answer:
= 184/5
Step-by-step explanation:
converting mixed numbers to fractions, our initial equation becomes,
44/5 × 2/11
Applying the fractions formula for multiplication you get,
= 924/5
Simplifying 924/5, the answer is
=184 4/5
The circumference of a circle is pi x diameter. Therefore, we can use this in reverse order as well.
I’ll be using 3.14 as pi, but if you need a more exact answer you can always use the pi function on a calculator.
37.68/3.14 = 12
Therefore, the diameter must be 12.
Since the radius is half the diameter, we can divide by 2 to find the radius.
12/2 = 6
Therefore, the radius of our circle is 6.
The area of a circle is equal to pi x radius squared.
Since we know our radius, we can solve.
Using PEMDAS, we know to use exponents first, so 6 squared is equal to 36.
From there, we can multiply.
36 x 3.14 = 113.04
And there we have your answer! 113.04 is the area of the circle.
Hope this helped :)
