A cylinder has diameter of 6 cm and a volume of 36 pi cm 3 . Find it's height and radius in centimeters
Answer:
Radius is 3
Height is 4
Step-by-step explanation:
First you'll have to find the radius
6/2=3
Then, use the formula Base (PI*radius squared)* height
To find the base, you'll have to use the radius, 3, times it by itself, 3, and get 9.
3*3=9
Then, multiply 9 by 3.14, first three digits of pi, and get 28.26
9*3.14=28.26
28.26=base
Now, you'll have to find the height
Since you know what the volume is 36 pi 3
36*3.14=113.04 <--volume without pi
Then, divide 113.04 (volume) by 28.26 (base) and get 4 (height)
113.04/28.26=4
That's why the radius is 3 and the height is 4
Answer:
r=3
h=4
Step-by-step explanation:

Find the length of side x I simplest radical form
Answer:
Option A
Step-by-step explanation:
By applying Pythagoras theorem in ΔABC,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
AC² = AB² + BC²
AC² = 6² + 5²
AC = [tex]\sqrt{61}[/tex]
Similarly, by applying Pythagoras theorem in ΔACD,
AD² = AC² + CD²
(10)² = [tex](\sqrt{61})^2[/tex] + x²
x² = 100- 61
x² = 39
x = √(39)
Option A will be the answer.
y=-4x-3
y=-2x+1
x=?
y=?
Answer:
x = -2
y = 5
Step-by-step explanation:
y = -4x - 3
y = -2x + 1 Multiply this whole equation by -1
-1(y = -2x + 1) = -y = 2x - 1
y = -4x - 3
-y = 2x - 1
0 = -2x - 4
4 = -2x
x = -2
y = -4x - 3 (Plug in x)
y = -4(-2) - 3
y = 8 - 3
y = 5

Ariana compró cierto número de sacos de azúcar por S/. 675 y luego los vendió por S/. 1 080, ganando S/. 3 por cada saco. ¿Cuántos sacos de azúcar compró?
Responder:
135
Explicación paso a paso:
Número de bolsas compradas = x
Costo total de compra = 675
Costo total de ventas = 1080
Beneficio por bolsa = 3
Por eso :
Beneficio total + costo total de compra = costo total de ventas
3x + 675 = 1080
3x = 1080 - 675
3 veces = 405
x = 405/3
x = 135
Se compraron 135 bolsas

28.In the year 2006, the number of malaria patients admitted in the hospital of a state was 4375. Every year this number decreases by 8%. Find the number of patients in the year 2008?
Answer:number of patients in the year 2008 =3,703 Patients.
Step-by-step explanation:
Number of malaria patients admitted in the hospital of a state in 2006= 4375.
Number of malaria patients admitted in the hospital of a state in 2007 if there was Decrease by 8% in 2007
= 8% x 4375 =350
4375-350=4,025 patients
Number of malaria patients admitted in the hospital of a state in 2008 since there was Decrease by 8% in 2008
8% x 4,025.= 322
4,025-322=3,703 Patients.

109
Step-by-step explanation:
Find the area of the composite shape below.
Answer: 1106.13 (2 decimal places)
Step-by-step explanation:
To work out the area of this composite shape you would have to put the two semi circles together to form a circle and work out the area of the circle (they have provided the radius which is 11in), then work out the area of the rectangle separately.
The formula for the area of a circle is πr^2 (pi x radius squared).
So when you put the numbers in the formula the area is πx11^2=380.1327111
Then to work out the area of the rectangle you would do base x height.
The height of the rectangle is the same as the diameter of the circle (the diameter is double the radius of a circle) which is 22in.
To find the area of the rectangle you do 22x33=726
So then to find the area of the whole shape you would have to add the area of the circle and the rectangle together.
726+380.1327111=1106.13 (2 decimal places).
A jar contains 660 beans. Of them, 440 are kidney beans and the rest are cranberry
beans. What is the ratio of kidney beans to all beans?

6. There are 785 students in the senior class. If there are 77 more females in
the class than males, how many male and female seniors are there?
... please solve this using if systems of equations
Answer:
there are 431 females and 354 males in the class
Step-by-step explanation:
Let the number of females student in the class be x
Let the males by y
If there are 785 students in the senior class, then;
x+y = 785 .... 1
If there are 77 more females in the class than males, then;
x = y+77 ....2
Substitute 2 into 1
y+77+y = 785
2y = 785 - 77
2y = 708
y = 708/2
y = 354
Since x = 785 - y
x = 785 - 354
x = 431
Hence there are 431 females and 354 males in the class
