Answer:
<em>52.5 Seconds</em>
<em></em>
Step-by-step explanation:
Let's call, her time for the third race, x.
To find the average (53.4), we add up all the values and then divide this total by the number of values.
So, we will set up our equation.
56.4 + 51.3 + x
> ------------------------ = 53.4
3
To get rid of 3, we will multiply both sides by 3.
> 56.4 + 51.3 + x = 160.2
> 107.7 + x = 160.2
We will subtract 107.7 from both sides to isolate x.
<h2>
> x = 52.5</h2><h2>

Answer:
≈ 12.57 units squared
Step-by-step explanation:
The area of a circle is denoted by: 
, where r is the radius.
Remember that diameter is twice the radius, so since the diameter equals 4, we know that the radius r = 4/2 = 2.
Now, plug this in: 
We can round 4pi to 12.57 units squared.
