The volume of a sphere whose diameter is 18 cm is

Mathematics
1 answer:
prohojiy [21]3 years ago
5 0

Answer:

  = 3052.08 cm^3

Step-by-step explanation:

Volume of a sphere is given by

V = 4/3 pi r^3

We know the diameter is 18

d = 2r

18 = 2r

Divide each side by 2

18/2 =2r/2

9 =r

V = 4/3 pi 9^3

V = 4/3 pi (729)

V = 972 pi

Approximating pi by 3.14

V =972 (3.14)

  = 3052.08 cm^3

Use the x-intercept method to find all real solutions of the equation -9^3-72^2-96x+36=3x^3+x^2-3x+8
Vadim26 [7]

Answer:

 x ≈ 0.290640965127

Step-by-step explanation:

y subtracting the right side of the equation, we get a function that is zero at a real solution for x. The only x-intercept is at approximately 0.290640965127.

___

The graph shows the x-intercept to be 0.2906. The value above was obtained by Newton's method iteration. The roots of this cubic will all be irrational.

X:y=5:3 and x+y=56<br> work out he value of x-y
Alex

Answer:14

Step-by-step explanation:

x+y=56

x:y=5:3

Sum of ratio=5+3

Sum of ratio=8

x=5/8x56

x=(5x56) ➗ 8

x=280 ➗ 8

x=35

y=3/8x56

y=(3x56) ➗ 8

y=168 ➗ 8

y=21

x-y

35-21=14

x-y=14
