Answer: surface area
Step-by-step explanation:
86.4+86.39 divided by 2=86.395
Volume of cylinder = pi r^2 h = 30 m^3
Volume of sphere = 4/3 pi r^3
now h = 2r ( given)
so volume of cylinder = pi r^2 * 2r = 2 pi r^3 = 30
pi r^3 = 15 so r^3 = 15/pi
therefore the volume of sphere = 4/3 pi * 15/pi = 4/3 * 15 = 20 m^3 Answer
Answer:
Step-by-step explanation:
multiply numerators with numerators and denominators with denominators
1) 7/12 x 8/1 = (7 x 8) / (12 x 1) = 56/12 simplify 56/12
= 56/12 = 28 / 6 = 14 / 3 = 4 and 2/3 = 4 and 8/12
2) 9 seeds picks out 3/4 of the seeds
9 x 3/4 = 9/1 x 3/4 = 9x3 / 1x4 = 27/4 = 6 and 3/4
I can't read the other ones but jus follow the examples above
