Answer:
0.7143ans
Step-by-step explanation:
y=1/x
y=k/x
k=yx
given x=3,y=5
k=5×3=15
when y=21
x=k/y
x=15/21=0.7143ans
Area = (angle/2π)*π*r^2 because the area of a sector is basically the total area (π*r^2) divided by the fraction of the whole (angle/2π). 2π = the whole of the circle in radians.
So for your problem Area = (5π/2/2π)*π*(4^2) = (5π/4π)*π*(16) = (5/4)*(3.14)*(16) = 20*(3.14) = 62.8
Hope this helps!
Answer:
