Answer:
∠Z ≈ 12°
Step-by-step explanation:
Using the Sine Rule in ΔXYZ
=
, that is
=
( cross- multiply )
48 × sinZ = 10 × sin96° ( divide both sides by 48 )
sinZ =
Z = (
) ≈ 12°
Answer:
Step-by-step explanation:
From the picture we find that the sphere and the cylinder has equal heights.
i.e. cylinder has height = 2r.
x,y and r form a right triangle with hypotenuse as r.
Hence pythagorean theorem is satisfied
Area of the cross section parallel to it is area of circle with radius y
=
Volume of cylinder when 2 cones removed =
Hence volume of sphere =
