A cylinder an a cone have the same volume.The cylinder has a radius of 2 inches and a height of 3 inches.The cone has a radius o

taurus [48]

Volume of a cone = (1/3) pi x r^2 x h

Volume of a cylinder = pi x r^2 x h

Volume of the cylinder = pi x 2^2 x 3 = 37.68 cubic inches

Now set the volume for the cone to the volume of the cylinder and solve for the height.

37.68 = (1/3) x pi x r^2 x h

37.68 = (1/3) x pi x 3^2 x h

37.68 = (1/3) x pi x 9 x h

37.68 = 9.42 x h

h = 37.68 / 9.42

h = 4

The height of the cone is 4 cm.

A hat is on sale for h dollars. The regular price is 7 times as much. Charlie has enough money to buy two hats at the regular pr

Nostrana [21]

Answer:

Charlie can buy 14 hats at the sale price

Step-by-step explanation:

Let

h ----> the sale price of the hat

x ---> the regular price of the hat

we know that

$x=7h$ ----> equation A

Two hats at the regular price is equal to multiply 2 by x

Multiply by 2 equation A both sides

$2x=(7h)*2$

$2x=14h$

2 hats at the regular price cost the same that 14 hats at the sale price

therefore

Charlie can buy 14 hats at the sale price

Answer:

12900

Step-by-step explanation:

umm first you write down the number of zeros (but only the zeros at last if a zero comes in middle or between other numbers, then you must have to multiply it) and then multiply the remaining numbers. I am not good at explaining. ;)

What is the answer to (( 5 x 12)/3)+30-50

SpyIntel [72]

I believe the correct answer is 0

Step-by-step explanation:

To solve this question, we use an abbreviation formula called BODMAS which is:

B = Brackets

O = Of

D = Division

M = Multiplication

A = Addition

S = Subtraction

We solve each element that is available in the order of the abbreviated letter.

1. We solve the brackets:

$(5\times12) = 60$

2. We solve the second bracket:

$(60\div3) = 20$

The equation now is $20+30-50$

3. We now solve addition first:

$20+30=50$

4. Now we solve the subtraction:

$50-50=0$

The answer then = 0
