Answer:
Option(1)
Step-by-step explanation:
By applying secant rule in the given right triangle,
secθ =
From the picture attached,
Opposite side of angle θ = 5 units
By applying Pythagoras theorem,
(Hypotenuse)² = (leg 1)² + (leg 2)²
= (10)² + 5²
= 125
Hypotenuse = √125
= 5√5
Now substitute these values in the expression of secθ,
secθ =
secθ = √5
Option (1) is the correct option.
Answer:
The volume of the sphere is
Step-by-step explanation:
we know that
The volume of cylinder is equal to
we have
substitute
simplify
Remember that
A sphere and a cylinder have the same radius and height
so
The height of cylinder is equal to the diameter of sphere
h=2r
substitute
-----> equation A
The volume of the sphere is equal to
substitute equation A in the formula of the volume of sphere
