Answer:
The volume is 25.1 cubic inches
Step-by-step explanation:
Given
--- base radius
--- height
Required
The volume (V) of the cylinder
This is calculated using:

So, we have:





Answer: 12 cm^2
Step-by-step explanation:
BC ==> Base of triangle
Divide the triangle in two parts:
BC/2=BC'
6/2=BC'
BC'=3
Distance formula: a^2+b^2=c^2
c^2-a^2=b^2
5^2-3^2=b^2
25-9=b^2
b^2=16
b=4 ==> height of triangle
Area of triangle=A. b=base. h=height
A=1/2 * b * h=
A=1/2 * 6 * 4
A=1/2 * 24
A=12 cm^2
Answer:
5.5
Step-by-step explanation:
B is the midpoint of AC, D is the midpoint of CE
This means that CE = 1/2 AE
CD = 1/2 ( 11)
CD = 5.5
Formula : Amount of change / Original amount
1. 144 - 90/ 144
2. Subtract 144 and 90
3. 54/ 144
4. Divide 54 by 144
5 0.375
6 Move the decimal two places to the right.
7. 37.5 %
Answer: 37.5% is the markup rate
Answer: C the set of all integers, the set of all rational numbers, and the set of all real numbers
Step-by-step explanation: The value of square root of 9 is ±3. This means that there two answers to square root of 9: 3 and -3.
As far as 3 is concerned, it is one of the elements of the natural number set. It is already known that natural numbers are also whole numbers, also integers, also rational numbers, and also real numbers.
As far as -3 is concerned, it is not a natural number since the set of natural numbers does not contain negative numbers. -3 is an integer. Which means that -3 is also a rational number and also a real number.
After identifying the common sets and taking the intersection of both the above classifications, it yields the set of all integers, the set of all rational numbers, and the set of all real numbers
