11. Answer:

LCM = 300

Explaination:

We will learn the relationship between H.C.F. and L.C.M. of two numbers.

The product of highest common factor (H.C.F.) and lowest common multiple (L.C.M.) of two numbers is equal to the product of two numbers.

H.C.F. × L.C.M. = First number × Second number

10 * LCM = 3000

LCM = 300

12: Answer: Second number = 352

Explaination:

Given lowest common multiple (L.C.M.) = 1760

Highest Common Factor (HCF) =32

First Number = 160

We find the second number.

Use the relation:

H.C.F. × L.C.M. = First number × Second number

32*1760 = 160 * second number

Second number = 352

Asphere which has a diameter of 6 inches has a volume of:

earnstyle [38]

Answer:

9.42 cubic inches

Step-by-step explanation:

In order to find the volume for a sphere, we use the formula V = πr. For the sake of simplicity, we will be using 3.14 for π. Before we plug anything in, let's get our radius. Remember, the radius is half of the diameter.

Equation: d = 2r

Replace: 6 = 2r

Divide: 3 = r

Now that we have our radius, let's plug in what we have and solve.

Equation: V = 3.14r

Replace: V = 3.14(3)

Multiply: V = 9.42

Remember, volume is measured in cubic units, so use cubic inches for the unit here.

A rectangular prism has a base with a length of 25, a width of 9, and a height of 12. A second prism has a square base with a si

RSB [31]

Answer:

The height of the second prism is 12 units.

Step-by-step explanation:

First, we must know that the volume of a rectangular prism is equal to length x width x height. With this information, we can multiply the given dimensions of the first rectangular prism to get a volume of 2700 cubic units. From here, we must understand wha we need from the second rectangular prism. Because it has a square base of 15, that accounts for both its width and length. Therefore, we have that

$Volume= 15^2 x\\2700/225=x\\12=x$
