Answer:
z * sigma+u = x
Step-by-step explanation:
z = (x-u)/ sigma
z is the z score, u is the mean, sigma is the standard deviation
We need to solve for x
Multiply each side by sigma
z * sigma = (x-u)/ sigma * sigma
z * sigma = x-u
Add u to each side
z * sigma+u = x-u+u
z * sigma+u = x

Answer:
volume = 24,501.42
Step-by-step explanation: the way i did it:
first find the radius, 34 divided by 2 = 17π
then multiply the radius by itself 17 x 17 = 289
after, multiply 289 by 27 to get 7,803
then multiply 7803 by 3.14 to get 24,501.42
Hope this is correct!
(p.s.) if you do it on a calculator and use the pi symbol (π) the answer would be 24,513.84
