We are given
area of sphere is 200.96cm^2
it means that we are given surface area
so, we can use surface area formula
where S is surface area
r is radius
so, firstly we need to find radius or r
we can solve for r
now, we can find volume
we can plug r
now, we can find volume
.............Answer
We can find this using the formula for arc length (where is the radius of the circle and
is the central angle in radians):
In our problem, we are given . This means that:
The measure of the angle is 1.5.
