Answer:
50.24
Step-by-step explanation:
diameter is 8 inches
radius is 4
formula:
area = pi times radius squared
area = pi times 4 squared
area = pi times (4 times 4)
area = 3.14 times 16
area = 50.24
Using the mean concept, it is found that on average, it takes him 11.9 seconds to run a 100 yard dash.
<h3>What is the mean?</h3>
The mean of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.
In this problem, the three observations are given by:
12.7 s, 11.2 s, 11.8 s.
Hence the mean is:
M = (12.7 + 11.2 + 11.8)/3 = 11.9.
On average, it takes him 11.9 seconds to run a 100 yard dash.

Answer:
x = 2
Step-by-step explanation:
the formula for this problem is
Area = 1/2 base x Height
step 1) plug in what we know
5 = 1/2 base(5)
step 2) switch sides
1/2 base x 5 = 5
step 3) divide both sides by 1/2 x 5
= 
step 4) Simplify
step 5) Simplify
step 6) now you have gotten the answer<u> x = 2</u>
Answer:
15.21= 15.2 when rounded
Step-by-step explanation:
the formula for finding the area of a circle with the diameter is
