Jamaal has 20 models of cars and planes. He has 3 times as many cars as planes. What is the ratio of cars to total models? Mutiply its what 20X20X20
Answer:
And replacing we got:
And the best option would be:
65.42 Inches cubed
Step-by-step explanation:
For this case we have the following info given:
represent the height of the cone
represent the radius
And the volume of the cone is given by;
And replacing we got:
And the best option would be:
65.42 Inches cubed
The capsule describe consists of 2 hemispheres (same) and 1 cylinder. We need to sum up the volume of the cylinder and the 2 same hemispheres.
- <u>Volume of Cylinder:</u>
We are given the radius of the cylinder as 3 and the height as 6. The formula for volume of cylinder is . Plugging in 3 for r and 6 for h gives us,
.
- <u>Volume of Hemisphere(s):</u>
We are given the radius is 3 for the hemisphere. The formula for volume of a hemisphere is half of the volume of a sphere. The formula for hemisphere is shown below.
. Plugging in 3 for r gives us,
<em>Now, since we have 2 same hemispheres, we multiply this answer by 2 to get total volume of the 2 hemispheres.</em>
.
- <u>Total volume of the capsule:</u>
In decimal, taking 3.14 as , it is
Rounding to the nearest whole number gives us 283 millimeters squared.
ANSWER: Volume = and
The operation one: to divide how many chips were eaten by a minute
do the math: 35.5 chips/ 15 minutes=2.3666... chips/min (chips per minute)
circle B since that's your final answer. (i rounded 2.3666... by the nearest thousandth and got 2.37)
*my bad i had to edit
It will not have any real solutions because it is not a full equation. it is missing the purpose of the equation, on what to do to it.
