V = 1/3* h * r^3 pi
V ' = 1/3* h/3* (2r)^3 pi = h/9 * 8r^3 * pi

V ' / V = (h/9 * 8r^3 * pi) ÷ ( 1/3* h * r^3 pi ) = (8 * 3)/ 9 = 8 /3

Solve for c 4(3+c)+c=c+4

Sonja [21]

Answer:

c = -2

Step-by-step explanation:

Given equation is :

4(3+c)+c=c+4

12 + 4c + c = c + 4

12 + 4c = 4 [dividing by 4]

3 + c = 1 [adding and subtracting 3]

c = -2

Rearrange the equation so u is the independent variable. 4u+8w=-3u+2w4u+8w=−3u+2w

stiv31 [10]

Answer:

Step-by-step explanation:

4u + 8v = -3u + 2v

Solving 4u + 8v = -3u + 2v

Solving for variable 'u'.

Move all terms containing u to the left, all other terms to the right.

Add '3u' to each side of the equation. 4u + 3u + 8v = -3u + 3u + 2v

Combine like terms: 4u + 3u = 7u 7u + 8v = -3u + 3u + 2v

Combine like terms: -3u + 3u = 0 7u + 8v = 0 + 2v 7u + 8v = 2v

Add '-8v' to each side of the equation. 7u + 8v + -8v = 2v + -8v

Combine like terms: 8v + -8v = 0 7u + 0 = 2v + -8v 7u = 2v + -8v

Combine like terms: 2v + -8v = -6v 7u = -6v

Divide each side by '7'. u = -0.8571428571v

Simplifying u = -0.8571428571v
