Answer:
12.62 m
Step-by-step explanation:
Area of a circle = πr²
Area = 125m²
Hence:
125m² = πr²
r² = 125m²/π
r = √125m²/π
Hence,
r =√ 39.788735773
r = 6.3078313051 m
Diameter = Radius × 2
Therefore, Diameter of one circle is
= 6.3078313051 m × 2
= 12.61566261m
Approximately = 12.62 m
Answer:
Volume is about 26.5 in^3
Step-by-step explanation:
The volume = 4/3 pi r^3 where r = the radius.
the radius = 1/2 diameter = 1/2 * 3.7 = 1.85 ins.
So V = 4/3 * 3.14 * 1.85^3
= 26.5084
Answer:
In a standard normal distribution
95% of the data is within 2 standard deviations of the mean.
have a nice day! (^o^)
First, isolate the variable
X+0=75-5
X+0=70
X=70
Hope I helped!
Good Luck!
Step-by-step explanation:
you first need to know what is mean .mean is when you add all the numbers up then divide them by 2
