Answer:

r=\sqrt{\frac{3V}{\pi\ h}}

Step-by-step explanation:

The volume of cone is given by:

V=\frac{1}{3}\pi\ r^2\ h

where r is the radius of the base and h is the height of the cone.

We need to solve for r

we have V=\frac{1}{3}\ \pi\ r^2\ h

Multiplying both sides by 3 to remove \frac{1}{3}

⇒ 3\times V=3\times \frac{1}{3}\ \pi\ r^2\ h

⇒ 3V=\pi\ r^2\ h

dividing both sides by \pi\ h

⇒ \frac{3V}{\pi\ h}=\frac{\pi r^2 h}{\pi\ h}

⇒ \frac{3V}{\pi\ h}=r^2

Taking square root both sides:

⇒ \sqrt{\frac{3V}{\pi\ h}}=\sqrt{r^2}

⇒ \sqrt{\frac{3V}{\pi\ h}}=r

∴ r=\sqrt{\frac{3V}{\pi\ h}}

2 number cubes are rolled what is the probability that the sum if the numbers rolled is either a 4 or a 10
goldenfox [79]
With 2 cubes, there are 3 ways to roll a sum of 4... 1 and 3, 3 and 1, 2 and 2.
with 2 cubes, there are 3 ways to roll a sum of 10....6 and 4, 4 and 6, 5 and 5.

total possible outcomes = (6 * 6 ) = 36

probability of this happening is 6/36 reduces to 1/6

Rosalie earns extra money by working as a babysitter over the weekend. She charges $10 to drive to the home and an additional $8
agasfer [191]

Answer: The input values are B-number of hours (x).

The output values are C-charge for babysitting(y).

The value of $10 represents the B-y intercept.

The value of $8 represents the C-slope.

Step-by-step explanation:

Charges to drive to the home= $10

Additional charges per hour=$8

Let x be the hour she worked (independent variable) and y be the total charge for baby sitting (dependent variable)

Thus, the input values are number of hours (x) and the output values are charge for babysitting(y)

According to the situation the equation would be

y=8x+10

which is equivalent to the slope intercept form y=mx+c, where

m=8, slope of line

At x=0, y=10

Thus, $10 represents the y intercept
