Answer:
"unchanged"
Step-by-step explanation:
Congruence transformations (translation, rotation, reflection) do not change lengths, angles, area (of 2D figures), or volume (of 3D figures). The area would remain unchanged.
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
Answer:
14
Step-by-step explanation:
5 time 8=40
40 = total
6 times 9=54
54-40=14
I hope this will help
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 />
Answer:
