if you want area of sector
[angle x pi x radius-square]/360
if you know area then you can find the radius or
The volume of a solid sphere is:
V = 4/3*π*R^3
Since the complete sphere goes all the way around (2*π radians), the fraction of the sphere you have is T / (2*π), if T is given in radians. Therefore, the volume of the sphere sector is:
V = (4/3*π*R^3) * (T / (2*π))
V = 2/3*T*R^3
then substitute the volume and get radius
or use integration ( cylindrical shell or disc method) by setting the equ of the sphere as equ of circle x^2+(y-h)^2+r^2
and set the x int as the end point of the sphere. The x intercept will be rsintheta
Finding area of sector means finding a fractional part of the area of the entire circle. The fraction is determined by the ratio of the arc length to the entire circumference.
I'm sorry, but i don't know =/.
It depends on what information you have: the radius and the area of the sector or the length of the arc.
Find the area of the shaded sector. radius of 3 ...A+ = 7.07

The area of a sector of a circle with radius 12 and arc length 10pi is: 188.5 square units.
The area of a sector in a circle if the radius is 4 cm and the arc has degree 120 is: 16.76 cm2
It depends on what else is known about the sector: length of arc, area or some other measure.
If you have the arc length:where:L is the arc length.R is the radius of the circle of which the sector is part.
If the sector of a circle has a central angle of 50 and an area of 605 cm2, the radius is: 37.24 cm
19.28
(pi * radius squared) * ( sector angle / 360 )
The answer depends on what information you do have: radius, arc length, central angle etc.
if a circle has a radius of 12cm and a sector defined by a 120 degree arc what is the area of the sector
