Answer:
188.57 cm³
Step-by-step explanation:
Half sphere = 1/2 volume sphere
Sphere = 4/3 * 22/7 * 3³
Sphere = 4/3 * 22/7 * 27/1
Sphere = 2376/21 = 113.14
113.14 / 2 = 56.57
Cone = 22/7 * 3² * h/3
Cone = 22/7 * 9/1 * 14/3
Cone = 2772/21 = 132
132 + 56.57 = 188.57 cm³

Answer: 30° and 330°
<u>Step-by-step explanation:</u>
sec θ = 
sec θ = 
=
cos θ = 
cos θ = 
cos θ = 
cos θ = 
Look at the Unit Circle to see that cos = at 30° and 330° ( which is equivalent to π/6 and 11π/6)
To evaluate this expression properly, we must follow order of operations (PEMDAS) rules. Here, that means doing exponentiation first, followed by mult. and div., followed by addition and subtraction.
2−4÷2+2^3 becomes 2−4÷2+8 after exponentiation.
2−4÷2+8 becomes 2-2+8 after division.
2-2+8 = 8
Your final value for this expression is 8.
