What’s the area of the sector
Stella [2.4K]

Answer:

Step-by-step explanation:

If the sector  wasn't there, the area would be that of a circle. The formula for a circle = pi * r^2

But the sector is there and so you have to account for it.

Area sector = (60/360) * pi * 11^2

Area sector = 1/6 * pi * 121

1/6 of 121 = 20.17

Area of sector = 20.17 pi square cm

It's 4/5....you just find out what each of the denominators are equal to....so they are both factors of 45......so you take the one with 2/5 and multiply by 9 on top and bottom   and then take 2/9 and multiply it by 5 on top and bottom so you have 18/45 and 10/45....so now you take the to and add them up to get 28/45 and now you can simplify if necessary <span />
