A right circular cylinder has a height of 2214 ft and a diameter 225 times its height.
Temka [501]

Answer:

Volume is 431288166770775 cubic feet.

Step-by-step explanation:

The height of the cylinder = 2214 ft

Let d be the diameter . Hence, we have

d = 225 × 2214 = 498150 ft

Hence, the radius should be half of diameter.

r=\frac{d}{2}\\\\r=\frac{498150}{2}\\\\r=249075ft

The volume of cylinder is given by

V=\pi r^2h\\\\V=3.14(249075)^2(2214)\\\\V=431288166770775ft^3

When does a linear equation have infinitely many solutions?
Kipish [7]

Answer:

An equation can have infinitely many solutions when it should satisfy some conditions. The system of an equation has infinitely many solutions when the lines are coincident, and they have the same y-intercept. If the two lines have the same y-intercept and the slope, they are actually in the same exact line.

There are 110 calories per 177.4 grams of Cereal X. Find how many calories are in 238.5 grams of this cereal
patriot [66]

Answer: 147.87 calories

Step-by-step explanation:

Let the amount of calories in 238.5 grams of this cereal be represented by x.

Based on the information given, we can form an equation as:

110/177.4 = x/238.5

Cross multiply

177.4 × x = 238.5 × 110

x = (238.5 × 110) / 177.4

x = 147.87

Therefore, there are 147.87 calories in 238.5 grams of this cereal.

The perimeter of a square newspaper ad is 40 centimeters. How long is each side?
Katyanochek1 [597]
The answer is:  "10 cm" .
____________________________________
Method 1)
____________________________________________
2L + 2w = 40 ;  Since the formula for perimeter of a rectangle (Note: a square is a rectangle) is:

                         P = 2L + 2w ;  Note:  L = length; w = width; P = perimeter;
______________________________________________________
 Factor out a "2":
_________________
" 2L + 2w = 40" ;

2 (L+ w) = 40;

Divide each side of the question by "2" ;
____________________________________
         [2 (L + w)] / 2  = 40 / 2 ;
____________________________________
 to get:  (L + w) = 20 ;

Note:  this "rectangle is a square" ; so L= w".
__________________
20 /2 = 10 ;

L + w = 10 + 10 = 20.

This is a square, so each side of the square is the same length.

Each side is:  10 cm .
______________________________________________
Method 2)
______________________________________________

We are given: The perimeter (sum of the lengths of all sides) of a square is "40 cm."  Since a square has 4 sides of equal length:
     Each side is:  40 cm / 4 = 10 cm.
