Answer:
The formula of the volume of a cylinder is known as follow
<h2>V= πr²h</h2>
Where
π is 3,14 or 22/7.
d (diameter) is a straight line segment that crosses a center and connects two points on the circle.
r is the radius of the to part of the cylinder.
h is the height.
we can subsitute to our formula knowing that
d = 4cm (turn to r = <em>2cm</em>,because the formula use r) ; h = 11cm
V = πr²h
= 3,14 × 2² × 11
= 3,14 × 4 × 11
= 3,14 × 44
= 138,16 rounded off (138,2cm3) result

Step-by-step explanation:
Answer:
y(y-2)(y+10)
Step-by-step explanation:
when factoring you work with similar concepts and get rid of what you can to make the equation simipler and get your answer like you take a y out of the equation to get y^2 and then reduce and then solve by grouping.
Answer:
-8a + 12
Step-by-step explanation:
-2(4a - 6)
-2(4a) - -2(6)
-8a - -12
-8a + 12
