Answer:

The volume of the cylinder is 2520.64ft³

Step-by-step explanation:

To calculate the volume of a cylinder we have to use the following formula:

v = volume

h = height = 19ft

π = 3.14

r = radius = 6.5ft

v = (π * r²) * h

we replace with the known values

v = (3.14 * (6.5ft )²) * 19ft

v = (3.14 * 42.25ft²) * 19ft

v = 132.665ft² * 19ft

v = 2520.64ft³

The volume of the cylinder is 2520.64ft³

Given the system of inequalities:
Margaret [11]
Answer:
First inequality: y > \frac{4}{5} x - \frac{1}{5}
Second inequality: y < 3 + x

Explanation:
The inequality in slope-intercept form has the following general formula:
y < mx + c or y > mx + c (according to the given sign)
where m is the slope and c is the y-intercept

This means that to get any inequality in slope-intercept form, we will have to isolate the y on one side of the inequality.

First given inequality:
4x - 5y < 1
4x - 5y + 5y < 1 + 5y
1 + 5y > 4x
1 + 5y - 1 > 4x - 1
5y > 4x - 1
y > \frac{4}{5} x -  \frac{1}{5}
comparing this to the general form, we would find that:
slope (m) = 4/5
y-intercept (c) = 1/5

Second given inequality:
y - x < 3
y - x + x < 3 + x
y < 3 + x
comparing this to the general form, we would find that:
slope (m) = 1
y-intercept (c) = 3

Hope this helps :)

As part of a new advertising campaign, a beverage company wants to increase the dimensions of their cans by a multiple of 1.10.
Firdavs [7]

Answer:

New can holds 112.25\,\,cm^3 more than the old can

Step-by-step explanation:

Given: Diameter of the can is 6 cm and height is 12 cm such that volume of can is 339.12\,\,cm^3

Dimensions of the can are increased by a multiple of 1.10

To find: Difference between the volume of new can and volume of old can

Solution:

Volume of can (v) = 339.12\,\,cm^3

Let r, h denote radius and height of the can.

Let R, H denotes radius and height of the new can.

r = diameter/2 = \frac{6}{2}=3\,\,cm

h = 12 cm

R = 3(1.1)=3.3.\,\,cm

H = 12(1.1)=13.2\,\,cm

New volume (V) = \pi (R)^2H=\pi(3.3)^2(13.2)=451.37\,\,cm^3

So,

V-v=451.37-339.12=112.25\,\,cm^3
