The figure RQTS is a clockwise rotation of figure DEFC, then:
The image of CD is
Answer: Option C. RS
The answer is:put the equation xa+yb=1 to the slope intercept form and find its slope and y-intercept.
The area of a sector of a circles is calculated by the equation A = πr^2 (theta/360). From the data of the sector, we determine the radius of the circle. THen, we can calculate for the area of the circle.
16.4π = πr^2 (72/360)
r = 9.06
Area of circle = πr^2
Area of circle = π(9.06)^2
Area of circle = 82π
