Answer:
3311.36ft^3
Step-by-step explanation:
Given data
Height h= 11.9ft
Radius=16.3ft
The expression for the volume of a cone is given as
Volume= 1/3πr^2h
substitute
Volume=1/3*3.142*16.3^2*11.9
Volume= 1/3*3.142*265.69*11.9
Volume= 1/3*9934.095962
Volume=3311.36ft^3
Hence the volume is 3311.36ft^3
Answer:
option (d) 16.6 and 21.4
Step-by-step explanation:
Data provided in the question:
The mean life for a particular use before they failed = 19.0 hours
The distribution of the lives approximated a normal distribution
The standard deviation of the distribution = 1.2 hours
To find:
The values between which 95.44 percent of the batteries failed
Now,
In Normal distribution, the approximately 95% ( ≈ 95.44% of all values ) falls within 2 standard deviations of the mean
Therefore,
Upper limit = Mean + 2 × standard deviation
⇒ Upper limit = 19.0 + 2 × 1.2 = 21.4
Lower limit = Mean - 2 × standard deviation
⇒ Lower limit = 19 - 2 × 1.2 = 16.6
Hence,
the answer is option (d) 16.6 and 21.4
Answer:
147
Step-by-step explanation:
whoa chill
114+33=147
180-147=33
180-33=147
1 gallon = 4 quarts
1 quart = 32 ounces
1 gallon = 128 ounces
9 gallons = 1,152 ounces
Filling 8 ounce cups = 1,152 / 8 = 144 cups
