Question

The area of sector whose length=
48m, radius=10m is____​

Answer 1

Answer:

area of sector=(48m/10πm)×100πm²

=480m²

hence the area of the sector is =480m²

Answer 2

Answer:

area of sector = 480m

Step-by-step explanation:

L = 48m

r = 10m

we know that

area of sector = arc length/circumference × area of circle

now,

       arc length = 48m

   

        circumference = 2$\pi$r

                                = 2$\pi$(10) m

                                =  10$\pi$m

         area of circle = $\pi r^2$

                              = $\pi (10)^2$

                              = $100\pi m^2$

put the value

area of sector = arc length/circumference × area of circle

                     = $\frac{48}{10\pi }$ × $100\pi$

                     = 480m
