Answer:
Area=576 cm²
Perimeter=123.4 cm
Step-by-step explanation:
We have to assume that ABCD would form a square and not a rectangle. If so, the area is simple: 24x24=576 (Just picture the half circle sliding into the empty space - it’s the same area.)
For the perimeter, we find it for the half circle first. 1/2(2)
(12)=37.7
Then add the top and bottom (24 and 24) to the left and right (37.7 And 37.7)
24+24+37.7+37.7=123.4
Answer:
The number 312 lies between the perfect cubes 216 and 343.
So the cube root of 312 lies between the number 6 and 7.
This means that the cube root of 312 is an irrational number because it is not a perfect cube root.

Answer:
x = -27
Step-by-step explanation:
5(x - 1) = 4(x - 8)
Distributive property
5x - 5 = 4x - 32
Subtract 4x from both sides
x - 5 = -32
Add 5 to both sides
x = -27
