Root3 a^2/4
Hope this helps.!!
Answer:
Step-by-step explanation:
ok so i wont give you the ancwers but all you need to do ia multiply all your numbers in to one
7k/3 = 21
x 3 x3
7k = 63
/7 /7
k = 9
(7(9)/3 = 21 = 63/3 = 21 = 21 = 21)
Answer:
x = 5
Step-by-step explanation:
3x - 2 = x + 8
Subtract x from each side
3x-x - 2 = x-x + 8
2x -2 = 8
Add 2 to each side
2x-2+2 = 8+2
2x = 10
Divide each side by 2
2x/2 =10/2
x = 5
V=π*r^2*h
therefore the height must be:
h=V/(π*r^2)
Insert your values:
h=45π/(π*3^2)=5
The height is 5.
