Is there a math question and can you show it please
Answer:
<u>The volume of the container is 37.7 cubic inches and the equation is π * r² * h/3, where r is the radius and h is the height of the cone.</u>
Step-by-step explanation:
Let's recall that the formula for finding out the volume of a cone is:
Volume of a cone = π * r² * h/3
Replacing with the real values, we have:
diameter = 4 inches ⇒ radius = 2 inches
Volume of a cone = 3.1416 * 2² * 9/3
Volume of a cone = 3.1416 * 4 * 3
Volume of a cone = 37.7 cubic inches

Answer:
x = -2
, y = 1
Step-by-step explanation:
Solve the following system:
{-2 x - y = 3 | (equation 1)
-9 x - y = 17 | (equation 2)
Swap equation 1 with equation 2:
{-(9 x) - y = 17 | (equation 1)
-(2 x) - y = 3 | (equation 2)
Subtract 2/9 × (equation 1) from equation 2:
{-(9 x) - y = 17 | (equation 1)
0 x - (7 y)/9 = -7/9 | (equation 2)
Multiply equation 2 by -9/7:
{-(9 x) - y = 17 | (equation 1)
0 x+y = 1 | (equation 2)
Add equation 2 to equation 1:
{-(9 x)+0 y = 18 | (equation 1)
0 x+y = 1 | (equation 2)
Divide equation 1 by -9:
{x+0 y = -2 | (equation 1)
0 x+y = 1 | (equation 2)
Collect results:
Answer: {x = -2
, y = 1
