Answer:
8835.73ft^3
Step-by-step explanation:
First:
Find area of the base circle.
Diameter is 15, so radius is 7.5
Area of the base circle is 56.25pi (use formula: A=pi(r)^2 ) (also ill convert pi into decimals only later)
next find the volume of the cylinder
height is 40 so volume = 56.25pi*40 = 2250pi
next find the volume of the dome at the top.
you know the radius is 7.5
Use volume of sphere formula below :
4
/3πr^3
=1767.15
alright now add the two bolded values
1767.15+2250pi
= 8835.73
hope this helps
What is the slope of the line through (-7,-8)(−7,−8)left parenthesis, minus, 7, comma, minus, 8, right parenthesis and (0,4)(0,4
ANEK [815]
Answer:
12/7
Step-by-step explanation:
When given two points, we can find the slope by using
m = (y2-y1)/(x2-x1)
= (4 - -8)/ (0 - -7)
= (4+8) / (0+7)
= 12/7
Answer:
Your answer is 120 degrees.
Step-by-step explanation:
Answer:
12.54 square miles
Step-by-step explanation:
Area of Parallelogram = Base x Height
In this case, Base = 3.3 mi and Height = 3.8 mi
Hence,
Area = 3.3 x 3.8 = 12.54 square miles
The score of 96 is 2 standard deviations above the mean score. Using the empirical rule for a normal distribution, the probability of a score above 96 is 0.0235.
Therefore the number of students scoring above 96 is given by:
