Step-by-step explanation:
If you add 0 to anything, you do not have anything new when you are finished. A is an identity.
When you multiply 1 times anything, you do not get anything new. B is an identity

Answer:
336 cubic cm
Step-by-step explanation:
Volume of cone + (Volume of Sphere/2)
V (cone) = (π
h)/3
= π
(12) ÷ 3
= 64π ≈ 201 cm
V (sphere) = 4/3π
/2
= [4/3π(4^3)] ÷ 2
= (256π/3) ÷ 2
≈ 43π ≈ 135
Answer:
A
Step-by-step explanation:
One thing to note is that the side opposite to the angle is taken as perpendicular
If we take 57 as angle then it's opposite side is perpendicular
While if we take 33 as angle x is the perp
