Answer:
8 π or
25.13 unit^3 to the nearest hundredth.
Step-by-step explanation:
(A)
The height of the shell is (2 + x - x^2) and the radius is (2 - x).
V = 2π ∫(2 - x)(x + 2 - x^2) dx between the limits x = 0 and x = 2.
= 2π ∫ (2x + 4 - 2x^2 - x^2 - 2x + x^3) dx
= 2π ∫ (x^3 - 3x^2 + 4 ) dx
= 2π [ x^4/4 - x^3 + 4x ] between x = 0 and x = 2
= 2 π [4 - 8 + 8 )
= 2 π * 4
= 8π
= 25.13 unit^3 to the nearest hundredth.
I think the answer might be B identify the initial amount
Answer:
ASA
Step-by-step explanation:
Angle BAC and angle CDE are congruent ( indicated by a single dashed dashed line on the angle )
Side AC and side DC are congruent ( also indicated by a single dashed line )
Angle DCE and angle BCA are congruent ( this is because they are vertical angles and vertical angles are congruent )
Hence, the two triangles are congruent because of the congruency statement ASA
( angle. side, angle )
