Answer:
Below in bold.
Step-by-step explanation:
(a) Volume = volume of the cylinder + volume of hemisphere
= pi r^2 h + 1/2 * 4/3 pi r^3
= pi 2^2 3 + 2/3 pi 2^3
= 12pi + 16pi/3
= 52pi/3
= 52pi/3 in^3
= 54.45 in^3 to nearest hundredth.
(b) Surface area = area of base + area of curved part + area of the hemisphere
= pi 2^2 + 3 * 2pi 2 + 2 pi 2^2
= 4pi + 8 pi + 12pi
= 24pi in^2
= 75.40 to nearest hundredth.
Answer:
f(-3) = -3
Step-by-step explanation:
replace x with -3 and solve
(-3)^4 = 81
3(-3)^3 = -81
(-3)^2 = 9
6 = 6
now solve
x^4 + 3x^3 – x^2 + 6
81 + (-81) - 9 + 6
-9 + 6
-3
