Formula for volume of cylinder:
V=πr²h
Here height, h= 5 units
Diameter, d= 4 units
So, radius, r= d/2 = 4/2 =2 units
Put values in formula.
V= (3.14)(2)²(5)
V=62.8 Cubic units

Answer: 62.8 cubic units

Consider the graph shown.
Butoxors [25]

Answer:

Slope=\frac{3}{4}

The equation of line is y=\frac{3}{4}x+1 .

Step-by-step explanation:

If a line passes through two points (x_1,y_1) and (x_2,y_2), then the slope of the line is

m=\frac{y_2-y_1}{x_2-x_1}

From the given graph it is clear that the line is passes through the points (0,1) and (4,4).

Slope=\frac{4-1}{4-0}

Slope=\frac{3}{4}

The

The slope intercept form of a line is

y=mx+b

where, m is slope and b is y-intercept

The slope of the line is \frac{3}{4} and y-intercept is 1, so the equation of line is

y=\frac{3}{4}x+1

Therefore, the equation of line is y=\frac{3}{4}x+1 .

What is the sum of two numbers is 45 and theire difference is 5
adelina 88 [10]

Answer:

let the two numbers be x and y

x+y=45(equation 1)

x-y=5(equation 2)

from equation (1) y=45-x(equation 3)

substitute 45-x for y in equation 2

x-(45-x)=5

x-45+x=5

x+x-45=5

2x-45=5

2x=45+5

2x=50

x=50/2

x=25

Juan is filling a tank. The graph shows the amount of water in liters) in the tank versus time (in minutes).
3241004551 [841]

Answer:

Step-by-step explanation:

To answer all the parts given find the equation of the line given in the graph.

Let the equation is,

y = mx + b

m = slope of the line

b = y-intercept

x = time

y = Amount of water

Slope of a line passing through two points (x_1,y_1) and (x_2, y_2) is,

m = \frac{y_2-y_1}{x_2-x_1}

Slope of the given line passing through (0, 80) and (1, 320)

m = \frac{320-80}{1-0}

m = 240

Y-intercept 'b' = 80

Therefore, y = 240x + 80 will be the equation.

a). At x = 0

y = 240(0) + 80

y = 80 liters

b). As the time is increasing amount of the water is increasing

Rate of increase in the water = Slope of the line

                                                = 240 liters per minute
