What is the volume of a cone with a radius of 6 cm and a height of 12 cm? Use 3.14 for pi. Round your answer to the nearest hundredth. (4 points) Group of answer choices 452.16 cm3 465.24 cm3 472.12 cm3 480.50 cm3

Answers

Answer:

The volume of a cone is $452.16\ cm^3$ .

Step-by-step explanation:

We have,

Radius of a cone is 6 cm and its height is 12 cm

It is required to find the volume of a cone. Volume of a cone is given by :

$V=(1)/(3)\pi r^2 h$

r is radius

h is height

Plugging all the given values in the above formula,

$V=(1)/(3)* 3.14*(6)^2* 12\n\nV=452.16\ cm^3$

So, the volume of a cone is $452.16\ cm^3$ .

Answer:

The volume of a cone is kp;m

The answer is 3 places to the left

A hot air balloon can hold up to 300 pounds of weight. The balloon's pilot weighs 140 pounds. How many 20-pound bags of sand (b) can also be carried by the hot air balloon? Select THREE options. (1) –2
(2) 0
(3) 5
(4) 8
(5) 10

Answers

The possible values of 20-pound bags of sand will be;

⇒ 0, 5, 8

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

A hot air balloon can hold up to 300 pounds of weight.

And, The balloon's pilot weighs 140 pounds.

Now,

Let number of possible values of 20-pound bags of sand = b

So, We can formulate;

⇒ 20b + 140 ≤ 300

Solve for b as;

⇒ 20b ≤ 300 - 140

⇒ 20b ≤ 160

⇒ b ≤ 8

Thus, The possible values of 20-pound bags of sand are;

⇒ 0, 5, 8

Answer:

Step-by-step explanation:

You subtract 300 from 140 to get 160 because the pilot adds the weight in already. Once you get 160 divides it by 20 to get 8. Each bag weighs 20 pounds, every bag you add will decrease the total the air balloon can carry, so anything 8 and less is good. (4), (5), and (0) should be your answer.
