leva [86]3 years ago
3 0

Answer:

11494.04cm³

Step-by-step explanation:

Volume of a sphere

V = 4/3πr³

you got a diameter of 28cm, so half of taht is the radius.

r = 14cm

plug in and solve

V = 4/3πr³

= 4/3π(14)³

= 11494.04cm³

As part of a new advertising campaign, a beverage company wants to increase the dimensions of their cans by a multiple of 1.10.
Margaret [11]

Answer:

Question 1 ) Difference of Volume = 112.25 cm³

Question 2) Volume = 6400π feet³

Step-by-step explanation:

<h3>As part of a new advertising campaign, a beverage company wants to increase the dimensions of their cans by a multiple of 1.10. If the cans are currently 12 cm tall, 6 cm in diameter, and have a volume of 339.12 cm3, how much more will the new cans hold? Use 3.14 for π and round your answer to the nearest hundredth.</h3>

Diameter = 6 cm

Radius = 3 cm

Height = 12 cm

If we increase the dimension by 1.10, new dimesnions are:

Radius = 3 · 1.1 = 3.3 cm

Height = 12 · 1.1 = 13.2 cm

Volume = (Area)(Height) = (πr²)(Height)

Volume = (π)(3.3²)(13.2)

Volume = 451.37 cm³

Difference of Volume = 451.37 cm³ - 339.12 cm³

Difference of Volume = 112.25 cm³

<h3>The circumference of a redwood tree trunk is 16π ft, and it is 100 ft tall. What is the approximate volume of the redwood tree trunk? </h3>

Circumference = 2πr = 16π = 2π(8) feet

Radius = 8 feet

Volume = Volume = (Area)(Height) = (πr²)(Height)

Volume = (π)((8²)(100)

Volume = 6400π feet³

21(z+50)= 1,071 distrbultive property
Harman [31]

Answer:

The value of z is 1.

Step-by-step explanation:

Given:

21(z+50) = 1071

We need to solve the problem using distributive property.

Solution:

For the given equation we will apply distributive property;

By Definition of Distributive property which states that;

"The distributive property lets you multiply a sum by multiplying each addend separately and then add the products."

example = a(b+c) = a\times b +a\times c =ab +ac

So we get;

21\times z + 21\times 50 = 1071\\\\21z + 1050 =1071

Now by using Subtraction property we will subtract both side by 1050 we get;

21z+1050-1050=1071-1050\\\\21z=21

Now Dividing both side by 21 by using Division property we get;

\frac{21z}{21}=\frac{21}{21}\\\\z=1

Hence The value of z is 1.
