Pi is the ratio of the diameter to the circumference
circumference/diameter=pi
that's why c=pid or c=2pir

The formula for finding a volume of a cone is
V=πr^2h(1/3)
Plug in the values the have given you and solve.
3.14(7)^2(3)(1/3)
approx. 153.86 cubic ft.
Okay!
1) Round both numbers -
2674 - 2700
1847 - 1800
2) Subtract 2700 and 1800
2700 - 1800 = 900
Therefore, the answer is 900
Answer:
Keeping in mind the 'x' is in numerator, i got the answer to be 6.
Step-by-step explanation:
2/7x + 1/2x = 40/7 - 1/6x
2/7x + 1/2x + 1/6x = 40/7
2/7x + (3+1)/6x = 40/7
2/7x + 4/6x = 40/7
2/7x + 2/3x = 40/7
(2*3)+(2*7) / (7*3)x = 40/7
(6+14) / 21x = 40/7
20/21x = 40/7
20x = 40*21/7
20x = 40*3
x = 40*3 /20
x = 2*3
x=6
