Answer:
452.16 unit^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2h
The radius is 6 and the height is 4
3.14 ( 6)^2 4
3.14 * 36 *4
452.16 unit^3
Solve for x right ? . if u find for x . the answer ís x=-2
Answer:
The solution is: (x, y) = (9, -7)
Step-by-step explanation:
Step 1: Solve one of the equations for either x = or y = . We will solve second equation for y.
x+y=3
y=3-x
Step 2: Substitute the solution from step 1 into the second equation.
3x+4(3-x)=5
Step 3: Solve this new equation.
3x+4(3-x)=5
3x+12-4x=3
-x+12=3
-x=3-12
x=9
Step 4: Solve for the second variable
y=3-x
y=3-9
y=-7
The solution is: (x, y) = (9, -7)
Answer:
22
Step-by-step explanation:

25-3=22
Answer:
4.5 cm.
Step-by-step explanation:
We have been given that circle O has a circumference of approximately 28.3 cm.
We will use circumference formula to solve for the radius of our given circle.
Upon substituting the measure of circumference in above formula we will get,
Therefore, the radius of circle O is 4.5 cm.
