The volume of a cone is 1/3 x pi x radius^2 x height, so after substituting the values, we have the equation 1/3 x 3.14 x 3^2 x 10, and we have 3^2 because the radius is half the diameter. First, 3^2 = 9, and 1/3 x 3.14 is approximately 1.046. 1.046 x 9 = 9.414, and lastly, 9.414 x 10 = 94.14. So the approximate volume of the funnel is 94.14.
The expression that she can use is 1/6 x 1/5
I hope this can help :)
Answer:
18%
Step-by-step explanation:
Express the ending population as a percentage of the starting population:
270000 divided by 330000=0.82
0.82 *100=82
subtract from the 100% we started with to get the percent decrease:
100% - 82% = 18

Answer:
5.779 x 10^-8 =0.00000005779
Step-by-step explanation:
The E-8 at the end means the number is multiplied by 10^-8.
So 5.779E-8=5.779 x 10^-8
A negative power means move the decimal place that many places to the left
So 5.779 x 10^-8 =0.00000005779
