Answer: lateral surface area = 119.4cm^2
r = 2 cm.
h = 9.5 cm.
Steps:
Lateral surface area of a cylinder = 2πrh
r = radius h = height π = pi
2π(2)(9.5)
2π(19)
38π = 119.38052
Answer:
The following system of equation has no solution.
Step-by-step explanation:
since both of them are equal to y, set them equal to each other:
3x+1=3x+7
if you subtract both sides by 3x, you get 1=7. That is a contradiction, so this has no solutions.
I believe the answer is, not positive though
(-30m+33)
Answer:17/18
Step-by-step explanation:
Answer:
these triangles some is 90°.
72°+2x=90°
2x=90°-72
2x=18
x=18/2
x=9
