Mathematics
1 answer:

8 0

Answer:

volume cone = 1/3 pi r^2 h

volume cylinder = pi r^2 h

Step-by-step explanation:

1.  Volume = 1/3 x pi x r^2 x h = 12 X pi

2.  100 pi = 1/3 x pi x r^2 x 12

r^2 = 25

r = 5 cm

3.  volume = pi x 16 X 5 = 80 pi cubic meters

4.  400 pi = pi x r^2 X 4

r^2 = 100

r = 10 yards

3m-5m-12=7m-88-5<br><br> plz show all work
hammer [34]
3m - 5m - 12 = 7m - 88 - 5

-2m - 12 = 7m - 88 - 5 

-2m - 12 = 7m - 93

-12 = 7m - 93 + 2m

-12 = 9m - 93

-12 + 93 = 9m

81 = 9m

9 = m

hope that helps, God bless!
