A cone has a diameter of 24cm and a volume of 2713cm3. What is best approximation of height of cone?

1 answer:

7 0

V=(1/3)hpir^2
aprox

d=2r
d/2=r
d=24
r=24/2=12

V=2713

2713=(1/3)hpi(12^2)
2713=(1/3)hpi(144)
2713=48pih
divide both sides by 48
56.5208=hpi
aprox pi=3.14
divide both sides by 3.14
56.5208/3.14=h=18.0003
height=18cm

The heat in the house is set to keep the minimum and maximum temperatures (in degrees Fahrenheit) according to the equation |x –

solniwko [45]

Answer:

Minimum temperature is 68.5 ° and maximum temperature is 76.5 °

Step-by-step explanation:

Given :

|x – 72.5| = 4.

When the Temperature of x is minimum So the Minimum temperature is

$|x - 72.5| = 4\\it\ can \ be \ written \ as \\72.5-x=4\\-x=4-72.5\\x=68.5$

When the Temperature of x is maximum So the Maximum Temperature is

$|x -72.5| = 4\\x-72.5=\ 4\\x=72.5+4\\x=76.5$

Therefore The minimum temperature is 68.5 ° and the maximum temperature is 76.5 °

if the lenght of a rectangle is (2x - 8) cm and the with is (x - 2) cm and the perimeter is 84 cm what is the value of the lengt

Oxana [17]

Answer:

Step-by-step explanation:

Perimeter = 84 cm

2*(length + width) = 84

2* (2x - 8 + x - 2) = 84

2*(2x + x - 8 - 2) = 84 {bring like terms together}

2*(3x - 10) = 84 {add/ subtract like terms}

Divide both sides by 2

$\frac{2*(3x-10)}{2}=\frac{84}{2}\\\\$

3x - 10 = 42

3x - 10 +10 = 42 + 10 {add 10 to both sides}

3x = 52

Divide by 3,

$\frac{3x}{3}=\frac{52}{3}\\$

x= 17 1/3

Length = 2x - 8

$=2*\frac{52}{3}-8\\\\=\frac{104}{3}-\frac{8*3}{1*3}\\\\=\frac{104}{3}-\frac{24}{3}\\\\=\frac{104-24}{3}\\\\=\frac{80}{3}\\\\=26\frac{2}{3}$
