Hello from MrBillDoesMath!
Answer:
2035.8 (approximately)
Discussion:
The volume of a cone or radius r and height h is given by the formula:
Volume = (1/3) Pi * r^2 * h. In our case this is:
V = (1/3) Pi * (18)^2 * 6
=(1/3) Pi * 324 * 6 => 324/3 = 108
= 108 * 6 Pi => 108 *6 = 648
= 648 * Pi => approximating Pi by 3.14
= 648 * 3.14
= 2035.8 (approximately)
Thank you,
MrB
Answer:
156
Step-by-step explanation:
While solving we will have to use the area formula of the rectangle, which is :A=w*l ; length*width=A.
Steps:
1)let’s consider that the shape is a full rectangle. => 16*12=192.
2)9*2=18 -> 18*2=36
3)192-36=156.
The mass of hydrogen atoms that measures 54 u is 89.64 x 10^-24
Analysis:
If 1 u = 1.66 x 10^-24, then 54 u = 54 x 1.66 x 10^-24 = 89.64 x 10^-24

Answer:
x = 12
Step-by-step explanation:
(6x-2) + 20 = 90
6x-2 = 70
6x = 72
72 / 6 = 12
x = 12
