The volume formula could be re-written to help understand this, as V = π*3r^2*3h. If you solve for this, you can conclude that the volume would be multiplied by 27.
Answer:
The top one is (3x−2)(x+5)
the bottom one is (3x−2)(3x+2)
Step-by-step explanation:
Area= length * width
Area= 5*4
Area= 20

First, find the mean. You'll need it to compute the variance.

The variance of the sample is then computed with the formula

The standard deviation is the square root of the variance, so
