Answer:7.5π
Step-by-step explanation:
Φ=360-90
Φ=270
Radius=r=5
Length of arc=Φ/360 x 2 x π x 5
Length of arc=270/360 x 2 x π x 5
Length of arc=0.75 x 2 x π x 5
Length of arc=7.5π
Answer:
405
Step-by-step explanation:
So he built 5/9 of the wall, than added the extra 180 bricks to finish the wall.
so 5/9 + 180 = 9/9
so 180 = 4/9 Because 5/9 + 4/9 = 9/9
So to figure out how many bricks are in the wall we want to know what 1/9 of bricks equals and to work this out we need to divide 180 by 4
which equals 45.
Now we know that 1/9 = 45
so now to figure out what 9/9 is just multiply 45 by 9 which equals 405
