Use the formula to solve the problem. Round to the nearest hundredth.

Zepler [3.9K]

Answer:

Volume of sphere = 4.186 cubic inches

Step-by-step explanation:

Radius of sphere = r = 1 inch

Volume of sphere = ?

The formula used is: $Volume\:of\:sphere=\frac{4}{3}\pi r^3$

Putting value of radius and π and finding volume:

$Volume\:of\:sphere=\frac{4}{3}\pi r^3\\Volume\:of\:sphere=\frac{4}{3}\times 3.14\times (1)^3\\Volume\:of\:sphere=\frac{4}{3}\times 3.14\times (1)^3\\Volume\:of\:sphere=4.186 \:cubic\:in$

So, Volume of sphere = 4.186 cubic inches

Substitution to solve the linear system

STALIN [3.7K]

y=4x+2. eq1

y=5x. eq2

4x=2-y

x=(2-y) /4

substitute in equation 2

y=5(2-y) /2

y=(10-5y)/2

4y=10-5y

9y=10

y=10/9

substitute in equation 2 or 1

substituting in equation 2

10/9=5x

x=10/45

x=10/45 y=10/9

you can verify it also.
