A circle has a sector with are of (17/2)pi and a central angle of (17/90)pi radians. What is the area of the circle? Either ente
r an exact answer in terms of pi or use 3.14 pi and enter your answer as a decimal.
1 answer:
This circle has a sector area of 17pi/2 and a central angle of 17pi/90.
So, the whole angle of the circle would be 2pi. To find the area of a sector, you can use the formula A=R*Angle
17pi/2= R* 17pi/90
R=45
A=45^2 * pi
A=90 pi or 282.6

is that what you mean
3/4 + 5/16
=12/16 +5/16
=17/16
=1 1/16
