Answer:
The volume of the cylinder would be 392.5 cubic centimeters (B)
Step-by-step explanation:
To find the volume of the cylinder, we will need to use the formula:
V = πr^2h
Since the value of the radius is always equal to r = d/2 we can just divide the diameter by 2. We can then plug in our values from the equation into the formula, so our new formula is now:
V = (3.14)(5)^2(5)
Following the order of opperations EMDAS, we start with exponents:
V = (3.14)(25)(5)
Then we move on to multiplication, going from the left side to the right:
V = (78.5)(5)
V = (392.5)
We now know that the volume of the cylinder is equal to 392.5 cubic centimeters.
Answer:
The formula for the volume of a cylinder is V = πr²h where r is the radius of the base of the cylinder and h is its height. Since the diameter of the cylinder is 10 cm, its radius is 5 cm. Substituting these values into the formula gives:
V = π(5)²(5) = 78.54 cm³
Rounding to the nearest hundredth gives 78.54 cm³ ≈ 78.5 cm³.
Therefore, the volume of the cylinder is approximately 78.5 cm³.

Answer:
28
Step-by-step explanation:
24/6=4 then take the 4 and multiply it by 7(other number in ratio) and you get 28
Answer:
C. a = 3
b = 7
c = -20
Step-by-step explanation:
x = -b+/- (sq) b^2 - 4ac.
Well the way to plug the numbers in is by using this equation: Ax^2 + Bx + C = 0
S if you use your equation : 3x^2 = 20 - 7x
First you have to move everything to one side.
So it'll look like this:
3x^2 = 20 - 7x
-20 -20
3x^2 - 20 = -7x
+7x +7x
3x^2 - 20 + 7x = 0
don't forget that... Ax^2 +Bx+ C= 0
3 = A
7 = B
-20 = C
To find the number of females in the class, we can start by calculating the number of males.
Given that 30% of the class are males, we can calculate it as follows:
Number of males = 30% of total number of people
= 30% of 30
= (30/100) * 30
= 9
Since we know that the total number of people in the class is 30, we can find the number of females by subtracting the number of males from the total:
Number of females = Total number of people - Number of males
= 30 - 9
= 21
Therefore, there are 21 females in the class.
3.125 h
6.25 h
200 h
7812.5 h
Answer:
1250 divided by 50 = 25 times 8 = 200 hours
