Answer:
Step-by-step explanation:
we know that
The volume of the figure is equal to the volume of cube plus the volume of the cylinder
step 1
Find the volume of the cube
The volume of the cube is equal to
we have
----> the length side of the cube is equal to the diameter of the cylinder
so
step 2
Find the volume of the cylinder
The volume of the cylinder is equal to
we have
substitute
step 3
The volume of the figure is equal to
Answer: 180cm^2
Explanation: First, multiply 1.5 by 1.2 to get the area of the rectangle in METERS, which is 1.8. Since the question is asking for the area in CENTIMETERS, multiply 1.8 by 100 (because 1 meter=100 centimeters) to get 180cm^2.
Hope that helped :)
Answer:
(0.63789 ; 1.38211 )
Given that:
Mean, xbar = 1.01
Standard deviation, s = 0.29
Sample size, n = 7
Confidence interval : xbar ± margin of error
Margin of Error = Tcritical * s/sqrt(n)
Degree of freedom (df) = n - 1 = 7 - 1 = 6
Hence Tcritical = 3.143
Margin of Error = 3.143 * 0.29/sqrt(6)
Margin of error = 0.37211
Lower boundary = (1.01 - 0.37211) = 0.63789
Upper boundary = (1.01 + 0.37211) = 1.38211
(0.63789 ; 1.38211 )

Step-by-step explanation:
diameter, d = 6ft
depth, h = 4.5ft
pi = 3.14
volume, v = pi × d^2/4 × h
=> v = 3.14 × 6^2/4 × 4.5
v =127.17 cu ft (D)
Answer:
a. 6(7) + 2(3)^2 = 60
b. (5(-18)/3)-2 = -32
c. (6(10))^2 - 10/5 = 3598
d. (1-3)(1+2) = -6
