Answer:
well in my school its that in honors math you are doing the math of next year kinda like ap math and regular your doing your school year math but im not fully sure if it works like that every where
Step-by-step explanation:
Answer:
1/2
Step-by-step explanation:
Cos 60 =
1/2 =
Multiplying both sides by 4
=> XZ = 2
Sin Y =
Sin Y =
Sin Y = 1/2
Volume of the cone = 1/3 pi * 3^2 * 4 = 12pi
Volume of the hemisphere = 4/3 pi 3^3 * 1/2 = 18pi
So the volume of the toy = 12pi + 18pi = 30pi = 94.25 cm^3 to nearest hundredth Answer
Surface area of hemisphere = 1/2 * 4 pi 3^2 = 18pi
Lateral Surface area of the cone = pi r l where l = slant height of the cone
Now l= sqrt ( 4^2 + 3^2) = sqrt25 = 5
So lateral S A = 3 * 5 * pi = 15pi
Surface area of the toy = 18pi + 15pi = 33pi = 103.67 cm^2 ( nearest hundredth) Answer
