Since 3 out of 5 doctors (60%) use brand X, solve for 60% of 2,000, which is 1,200 doctors.

The diameter of the base of the cone measures 8 units.

kati45 [8]

Answer: $32\pi$ cubic units.

Step-by-step explanation:

You can use this formula for calculate the volume of a cone:

$V_{cone}=\frac{1}{3}\pi r^2h$

Where "r" is the radius and "h" is the height.

You know that the diameter of the base of the cone measures 8 units, then, the radius can be found by dividing the diameter by 2:

$r=\frac{8units}{2}\\\\r=4units$

Since you already know that height and the radius, you can substitute them into the formula. Then, the volume of this cone is:

$V_{cone}=\frac{1}{3}\pi (4units)^2(6units)$

$V_{cone}=32\pi \ units^3$

How do you convert a mixed fraction to an improper fraction ?

maks197457 [2]

Answer:

see the explanation

Step-by-step explanation:

we know that

A mixed number is equal to sum a integer plus a fraction less than 1. The result is a fraction where the numerator will be always greater than the denominator (This fraction is called an improper fraction)

Example

$a\frac{b}{c}$ ----> a mixed number

a is a integer

b/c < 1

so

$a\frac{b}{c}=a+\frac{b}{c}$

Adds the integer plus the fraction

$\frac{ac+b}{c}$ ---> an improper fraction

$\frac{ac+b}{c} > 1$
