D I think sorry if it's wrong :(
Assuming your looking for volume.
The following formula is used for calculating the volume (V) of a cone.
- where r is the radius and h, the height.
- Substitute r = 3 and h = 5 into the formula.
⇒ 
≈ 
The answer is 12. If you read from left to right, the numbers go up 12, if you go from right to left, they go down 12. Hope this helps!
Answer:
The answer is x=10
Step-by-step explanation:
Answer:
y = -3
Step-by-step explanation:
{y = x/2 - 4
y = 1 - 2 x
Substitute y = x/2 - 4 into the second equation:
{y = x/2 - 4
x/2 - 4 = 1 - 2 x
In the second equation, look to solve for x:
{y = x/2 - 4
x/2 - 4 = 1 - 2 x
Add 2 x + 4 to both sides:
{y = x/2 - 4
(5 x)/2 = 5
Multiply both sides by 2/5:
{y = x/2 - 4
x = 2
Substitute x = 2 into the first equation:
{y = -3
x = 2
