Answer:
9 units²
Step-by-step explanation:
A differential of area is ...
dA = ((2y -y²) -(y² -4y))·dy = (-2y² +6y)·dy
The indefinite integral of this will be ...
a = -2/3y³ +6/2y²
Then the definite integral over the limits [0, 3] will be ...
(-2/3·3³ +3·3²) - 0 = 9 . . . . square units

Answer:
2700pi
Step-by-step explanation:
The radius of cylinder is 15 meters and the height is 12 meters.
The volume of cylinder is
V =
Where, r is radius and h is height.
Substitute r = 15 and h = 12 in the volume formula.
V =
V = 2700
The volume of the cylinder is 2700 m³.
Answer:
Step-by-step explanation:
W2 - 2w + 3
Putting value when w = 5
(5)2 - 2(5) + 3
