Answer:
9/40
Step-by-step explanation:
- Write down the percent divided by 100 like this:
22.5/100
- Multiply both top and bottom by 10 for every number after the decimal point:
- As we have 1 digit after the decimal point, we multiply both numerator and denominator by 10, or, simply shift 1 decimal place to the right. So,
(22.5*10)(100*10)= 225/1000
- Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(225,1000) = 25.
225 ÷ 25/ 1000÷25 = 9/40
The second reflection image would be x.
<em>200.96 cm^3</em>
Step-by-step explanation:
The equation for the volume of a cone is...
Since we are using 4 for the radius we can plug that in, along with 12 for the height and 3.14 for pi.
So the equation with everything plugged in will be...
Now we can solve.
The volume of the cone is...
<em><u>200.96 cm^3</u></em>
