Answer:
Step-by-step explanation:
According to the diagram, the radius of this cyl. is 3 and the height is 4 (not 5). The formula for the volume of a cylinder is:
V = pi*r^2*h.
Here, that volume is V = pi*3^2*4, or 36 pi cubic units. That's Answer B.
The volume of the right cylinder is
Further explanation:
The formula for the volume of the cylinder can be expressed as,
Here, ‘r” represents the radius of the cylinder and “h” represents the height of the cylinder.
Given:
The radius of the cylinder is and the height of the cylinder is and the slant height is
The options of the volume are given as follows.
A.
B.
C.
D.
Explanation:
The volume of the right cylinder can be obtained as follows,
The volume of the cylinder is
Option A is not correct.
Option B is correct.
Option C is not correct.
Option D is not correct.
Hence, the volume of the right cylinder is

Zara ate 50 almonds last week which is 150% as many as she ate last week.
The percentage is defined as a ratio expressed as a fraction of 100.
We have been given that Zara ate 75 almonds this week, or 150% as many as she ate last week.
Let's assume that she eat x almonds last week
As per the given question, we can write the percentage would be as
⇒ 150% of x = 75
⇒ (150/100) x = 75
Apply the cross-multiplication operation,
⇒ 150x = 7500
Divided by 150 into both sides of the above equation,
⇒ x = 7500/150
⇒ x = 50
Therefore, she eat 50 almonds last week.

Answer:
Option 1st is correct
area of a triangle is, 80 in²
Step-by-step explanation:
Area of triangle(A) is given by:
where,
b is the base
h is the height or altitude of the triangle respectively.
As per the statement:
Base of a triangle(b) = 10 inches and
Height = altitude(h) = 16 inches
Substitute these in [1] we get:
⇒in²
Therefore, the area of a triangle is, 80 in²
B:7.3893
C:7.389
D:738.9
The numerical constant 'e' equals approximately 2.71828. If we square 'e,' we get the approximate value of 7.38905. Rounding to three decimal places, the correct answer is 7.389.
The constant e is an essential numerical constant that is the base of the natural logarithm. It is approximately equal to 2.71828. When you want to find the value of e^2, meaning 'e' squared, you multiply 'e' by itself.
To find the value to 3 decimal places, we operate: 2.71828 * 2.71828= 7.38905.
Therefore, rounding to 3 decimal places, e^2 is equal to 7.389. So, the correct answer to your question is option C: 7.389.

Don’s wires measure 3 inches, 5 inches, and 12 inches.
Margo’s wires measure 6 inches, 8 inches, and 14 inches.
Sonji’s wires measure 12 inches, 8 inches, and 17 inches.
Liam’s wires measure 16 inches, 8 inches, and 27 inches.
Which student chose pieces that can be used to construct a triangle?
a. Don
b. Margo
c. Sonji
d. Liam
Answer:
C. Sonji
Step-by-step explanation:
Since, a triangle is possible if the sum of any two sides is greater than third side,
The measure of Don’s wires,
3 inches, 5 inches and 12 inches
Since, 3 + 5 < 12
Thus, by the above statement we can not make a triangle with The measure of Don’s wires.
The measures of Margo's wires,
6 inches, 8 inches and 14 inches,
Since, 6 + 8 = 14,
⇒ we can not make a triangle with The measure of Margo's wires.
The measures of Sonji's wires,
12 inches, 8 inches, and 17 inches,
12 + 8 > 17,
8 + 17 > 12
12 + 17 > 8
⇒ we can make a triangle with the measure of Sonji's wires.
The measures of Liam’s wires,
16 inches, 8 inches, and 27 inches
16 + 8 < 27
⇒ we can not make a triangle with The measure of Liam’s wires.
Hence, option 'C' is correct.
