Answer 20

Ok

Answer 21

Well right now have no questions

Answer 22

okay

Answer 23

looks like you did right 8.776

pi.r² + 100.pi.r - 3000 = 0 that is the equation(lateral + base is about 3000)

Answer 24

oh, maybe i plugged it in wrong?

Answer 25

when it says explain the method you would use to solve this problem or whatever what should i put?

Answer 26

Curved surface area = 2.pi.r.h
the base pir^2, you added these together and set it equal to the given
from that you subtracted 300 both sides
so you were left with a quadratic equation
after solving the quadratic --
x>0 is the answer you chose, since r must be +

Answer 27

the method hmmmmm?

solving the quadratic

Answer 28

Okay thank you so much! i just really suck at math! I may tag you in another problem if i have another i cant figure out.
