volume = 4/3 x pi x r^3
r^3 = 12.3^3 = 1860.867
1860.867 x 4/3 = 2481.156
answer = 2481.156pi cm^3
Answer is A
Answer: V = 1,436.03 cubic meters
Step-by-step explanation:
V = (4/3)(3.14)(r^3)
V = (4/3)(3.14)(7^3)
V = (4/3)(3.14)(343)
V = 1,436.03
Due to given condition we can conclude:
H = 2D
where D is diameter of base and H height of cone
Volume of cone is calculated by:
V = B*H = r^2*pi*H
Now we need to express H in terms of r. H = 2D = 2*2*r because D = 2r
V = r^2*pi*4r = 4r^3*pi

Answer:
x = -10/3
Step-by-step explanation:
2/3x + 2/3 + 1/5x = 2/3x
Subtract 2/3x from each side
2/3x-2/3x + 2/3 + 1/5x = 2/3x-2/3x
2/3 + 1/5x = 0
Subtract 2/3 from each side
2/3 -2/3+ 1/5x =0- 2/3
1/5x = -2/3
Multiply each side by 5
5*1/5x = 5*-2/3
x = -10/3
